On the 2013-2025 RAM 2500 6.7 Cummins, the 2013+ RAM 2500 6.7L Cummins diesel DEF (Diesel Exhaust Fluid) system is plagued with failures of the DEF heater, DEF pump, DEF injector, NOx sensors, and SCR catalyst. The DEF system is required for emissions compliance, and when it fails, the truck enters a "limp mode" that limits speed to 5 mph after a countdown timer expires. DEF heater failures are most common in cold climates where the fluid freezes and cracks the heater element. TSB 18-018-20 addresses DEF heater and quality sensor issues. The NOx sensors (inlet and outlet) fail frequently at $300-500 each.
Common Symptoms
DEF system warning light or message
Speed limited to 5 mph (limp mode)
Check engine light with SCR-related codes (P20EE, P2BAD, P2201)
DEF quality poor message despite fresh fluid
DEF tank not reading correct level
Truck will not restart after shutdown (DEF lockout)
Ammonia smell from exhaust
How to Fix
Diagnose with Cummins INSITE or wiTECH to identify the specific DEF component failure. Common repairs: DEF heater replacement ($400-800, Mopar 68322877AA), DEF pump/injector assembly ($600-1,000), NOx sensor replacement ($300-500 each, two sensors). If SCR catalyst is failed, replacement costs $2,000-3,500. Check TSB 18-018-20 for updated DEF heater and quality sensor procedures. Use only API-certified DEF fluid (ISO 22241 standard). Avoid storing DEF over 1 year as it degrades.

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the Holset HE351VE variable-geometry turbocharger uses an electronically controlled actuator (the geartrain and control board that moves the vane sliding ring) that is a well-documented failure point, often before 100k miles. Soot and carbon buildup, rust/corrosion binding the vane arm, worn actuator gears, or a corroded circuit board (from coolant/water intrusion) cause the actuator to stop positioning the vanes correctly. The truck then either spools quickly but chokes at mid/high rpm or spools slowly with a big loss of low-end torque, and typically drops into limp mode. Owners on Cummins forums report repeat failures and note the unit must be scan-tool programmed to the specific turbo after replacement.
Common Symptoms
Loss of power / limp mode
Slow or no turbo spool
Excessive turbo whistle or lack of boost
Check engine light with turbo actuator codes
Sluggish acceleration when towing
Actuator gear grinding/clicking on startup
How to Fix
Replace the VGT actuator with a genuine remanufactured Holset unit (common OEM/service PNs for 2007.5-2012: 2837675 / 4034315HX / 4046534 / 4049828; later 2013-2018 trucks use the updated HE300VG actuator). The new actuator MUST be calibrated/aligned and programmed to the turbo with a Cummins-capable scan tool (wiTECH) or a pre-programmed 'corded' plug-and-play unit such as the BD Diesel corded HE351 actuator. If the vane mechanism itself is seized with soot the whole turbo may need replacement. Clean the vanes/EGR side and address coolant leaks that corrode the board to prevent recurrence.

On the 2014-2024 RAM 2500 6.4L 392 HEMI V8 gas, gas RAM 2500s with the 6.4L (392) HEMI V8 suffer a documented valvetrain defect in which the roller lifter needle bearings fail, the roller stops rolling and drags across the camshaft lobe, wiping out the lobe. The failure is linked to the truck's Multi-Displacement System (MDS/cylinder deactivation): when cylinders are deactivated, oil delivery to the affected lifters is restricted, starving the roller bearings. Owners report onset as a metallic 'HEMI tick' progressing to misfire, dropped cylinder and catastrophic top-end damage. A class-action lawsuit (Petro, et al. v. FCA US LLC, Case No. 1:22-cv-00621, whose named plaintiffs include a 2020 RAM 2500 owner) alleges FCA knew of the defect since at least 2012 and failed to disclose it. There is no safety recall, so repairs typically fall on the owner once warranty lapses.
Metallic ticking/tapping from top of engine (HEMI tick)
Engine misfire, rough idle
Check engine light with misfire codes
Loss of power / dropped cylinder
Metal shavings in oil
Loud knocking as failure progresses
How to Fix
Diagnosis via oil-analysis metal content, cylinder-specific misfire/lifter tick, and cam inspection. Accepted repair is replacement of all 16 lifters plus the camshaft (and any damaged pushrods/rockers); severely scored cams or circulated bearing debris often force a long-block or complete engine replacement. Many owners/shops disable/delete MDS during the rebuild to prevent recurrence. Frequent oil changes with correct-spec oil are the preventive measure.

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the intake grid (air) heater warms incoming air for cold starts and carries up to ~200 amps through a small threaded stud/bolt secured by a 10mm nut on the intake plenum. Over years of high-current heat cycling the bolt/nut connection deteriorates, arcs, and can break loose. Because it sits directly above the intake runner, gravity pulls the heavy steel stud straight into cylinder #6, destroying the piston, valves, and cylinder head, often the entire engine. Banks Power has documented 200+ failures, some at as little as 40,000 miles. Stellantis has NOT recalled the grid heater assembly itself (a separate 2021-2022 relay recall Y08/Y76 addressed sticking relays, not the bolt).
Common Symptoms
Loud engine knock / metallic clatter
Sudden power loss
Rough running or misfire on cylinder 6
Loose grid heater power terminal
Check engine light with grid heater codes
Hard cold starts
How to Fix
Do the preventive 'wiggle test': with the engine off, grab the external power terminal (10mm bolt) and try to move it; any movement means the internal stud is loosening and needs immediate attention. Best fix is to replace the stock grid heater with a redesigned unit that eliminates the internal bolt, such as the BD Diesel Killer Grid Heater upgrade kit (PN 1041520, fits 2007-2024), or install a grid-heater delete/relocation plate (Fleece/Pusher) if legal in your area. Genuine Cummins intake air heaters (e.g., 3970000 / 3970001) are direct replacements but retain the original design.

On the 2006-2018 RAM 2500, the TIPM is the central under-hood fuse/relay and power-distribution computer that controls the fuel pump, lighting, wipers, door locks, horn, and trailer-tow circuits. It is a widespread failure point on 2007-2016 Ram trucks. The most common complaint is the internal fuel pump relay sticking: stuck ON causes overnight battery drain and the pump running with the key off, while stuck OFF causes intermittent no-start / stalling. Other failures include inoperative wipers, dead door locks, non-working turn signals/high beams, phantom horn, and dead trailer lights. Root causes include water intrusion into the layered module and improperly spliced aftermarket accessories overloading circuits.
Fuel pump runs with key off / dead battery overnight
Wipers, door locks, or horn inoperative
Turn signals or headlights not working
Trailer tow lights dead
Random electrical gremlins / stalling
How to Fix
Diagnose which circuit is affected before replacing. A stuck fuel pump relay can be temporarily addressed with an external fuel-pump relay bypass harness, but the durable fix is to rebuild the existing TIPM (specialist shops like Circuit Board Medics repair the boards/relays) or replace it with a new module that must be programmed to the VIN. Remove any improper accessory splices feeding off TIPM circuits. Inspect for and seal water intrusion at the module.

On the 2014-2018 RAM 2500, 2014-2018 RAM 2500 heavy-duty pickups are covered by FCA recall 18V332000. The recall addresses a defect that could prevent the cruise control system from disengaging: if a short circuit occurs within the truck's wiring while cruise control is engaged, the driver may not be able to shut the system off with the brake pedal or with the cruise control switch. The 2500 will then maintain its speed or possibly accelerate. On a three-quarter-ton truck that is often loaded or towing, an inability to cancel cruise control is particularly serious, and NHTSA lists the consequence as an increased risk of a crash.
Common Symptoms
Brake pedal does not cancel cruise control
Cruise control system cannot be turned off manually
Truck holds speed or accelerates with cruise control on
How to Fix
Repair is free at any RAM dealer. The dealer inspects the software and performs a software flash on the engine or powertrain control module — no hardware is replaced. Owner notification started June 4, 2018; Chrysler customer service is 1-800-853-1403. Verify your VIN at nhtsa.gov/recalls before towing again if you are unsure whether the flash was performed. Until then, do not use cruise control. If the system will not disengage while driving, brake firmly and steadily, shift the transmission to neutral, and place the truck in park after it stops.
On the 2013-2015 RAM 2500, 2013-2015 RAM 2500 pickups were included in FCA US LLC's recall of vehicles fitted with radios containing software vulnerabilities. The defect allows third-party access to certain networked vehicle control systems, and NHTSA's consequence statement is blunt: exploitation can result in unauthorized remote modification and control of vehicle systems, raising the risk of a crash. This is a cybersecurity defect rather than a mechanical one — nothing wears out, and there is no maintenance that prevents it. The campaign covers 1,416,903 vehicles in total across all the Chrysler, Dodge, Jeep and RAM models named in it.
Common Symptoms
Vehicle systems responding to commands the driver did not give
How to Fix
Dealers install a Uconnect software update that eliminates the vulnerability, free of charge. Chrysler also mailed owners a USB drive with the update so it could be applied at home, and made the same update available for download at driveuconnect.com/software-update. As a stopgap, Chrysler had the wireless service provider close the open cellular connection to the vehicle. On a used 2013-2015 RAM 2500 there is no way to tell by looking whether a prior owner ran the update, so check the VIN at nhtsa.gov/recalls and let a RAM dealer flash it if the recall still shows open.
On the 2013-2018 RAM 2500, rAM 2500s fitted with the Uconnect 8.4-inch (RA3/RA4) head unit commonly suffer software and hardware faults: the touchscreen freezes or lags, the radio spontaneously reboots (audio cuts out and the Ram logo reappears), and some units fall into a continuous boot loop restarting every ~10 seconds (owners tie reboot loops to SiriusXM Travel Link and failed software updates). Separately, 'ghost touch' — the capacitive screen registering phantom inputs — is a hardware failure of the optically-clear adhesive (LOCA) between the digitizer and LCD that heat/sun break down, and no software reset fixes it. The problems span multiple model years and are a well-known chronic complaint.
Common Symptoms
Frozen/unresponsive touchscreen
Spontaneous radio reboots
Continuous restart / boot loop
Ghost-touch phantom inputs
Backup camera or SiriusXM not responding
Screen lag
Screen bubbling/delamination
How to Fix
For freezes/reboots, first-line fix is a soft/hard reset (press-and-hold the volume/tuner knobs ~10-20 seconds) and installing the latest Uconnect software update. Persistent ghost-touch is hardware: replace the touchscreen digitizer (glass only, ~$50-150, no dealer programming) or the full head unit; a Mopar reman full unit must be VIN-programmed and dealer swaps run ~$1,500-2,000.

On the 2003-2025 RAM 2500, the RAM 2500 (and 3500) with solid front axle experiences a violent front-end oscillation known as "death wobble" that occurs at highway speeds (45-65 mph), typically triggered by hitting a bump or pothole. The steering wheel shakes uncontrollably and the entire front end vibrates violently, making the truck nearly undrivable until the driver slows to a stop. The issue is caused by worn or loose front-end components working together in resonance: track bar, ball joints, tie rod ends, unit bearings, steering stabilizer, and steering gear box. NHTSA has received thousands of complaints. TSB 19-001-14 REV.B addresses front axle steering linkage inspection.
Common Symptoms
Violent steering wheel oscillation at highway speed
Entire front end shaking after hitting a bump
Steering wheel impossible to control during wobble event
Must slow to a stop to regain control
Wobble typically occurs between 45-65 mph
Front tires showing uneven wear patterns
Loose or clunking feeling in front end over bumps
How to Fix
Death wobble is a SYSTEM issue - all front-end components must be inspected. Start with: 1) Track bar and track bar bracket (most common initiator) - replace with upgraded aftermarket (Synergy, Carli) $200-400. 2) Ball joints - replace with Dynatrac or Synergy heavy-duty units $300-600/pair. 3) Tie rod ends - Moog or Synergy $100-200/pair. 4) Unit bearings - Timken or Moog $200-400/pair. 5) Steering stabilizer - Fox or Bilstein dual stabilizer $200-400. 6) Steering gear box - check for play, tighten or replace $400-1,200. Address ALL worn components, not just one. TSB 19-001-14 REV.B covers the inspection procedure.

On the 2003-2025 RAM 2500, the RAM 2500/3500 steering gear box (power steering box) develops fluid leaks from the input shaft seal and sector shaft seal, and excessive play in the steering. The leak starts as a slow drip and worsens over time, eventually causing low power steering fluid and potential pump damage. Excessive play manifests as a "dead zone" in the steering where the wheel moves 1-2 inches without the wheels turning. The gear box also loosens from the frame due to the high stresses of the solid front axle design. Tightening the adjustment screw on the gear box can temporarily reduce play, but eventual replacement is needed.
Common Symptoms
Power steering fluid leak at steering gear box
Excessive play or looseness in steering wheel
Dead zone when turning steering wheel
Wandering on highway - constant steering corrections needed
Whining noise from power steering pump (low fluid)
Steering gear box loose on frame mount
Power steering fluid on ground under truck
How to Fix
For minor leaks: Try a power steering stop-leak additive as a temporary fix ($15-20). For the input shaft seal leak, the seal can be replaced without removing the gear box ($100-200 labor). For excessive play: Adjust the sector shaft screw (1/4 turn clockwise) per TSB procedure - this takes up slack but is a temporary fix. For complete resolution, replace the steering gear box with OEM Mopar (68164717AA) or upgraded RedHead Steering Gear ($800-1,500 installed). Retorque or replace frame mounting bolts (they stretch over time).

On the 2010-2025 RAM 2500, the rear driveshaft U-joints in the RAM 2500 fail prematurely, particularly on trucks used for towing. The factory U-joints are undersized for sustained heavy load use, and the grease fittings (where present) are often overlooked during maintenance. Symptoms start with a clicking or clunking sound during acceleration and deceleration, progressing to vibration at highway speed. Complete U-joint failure can cause the driveshaft to drop, which is a serious safety hazard.
Common Symptoms
Clunking noise during acceleration and deceleration
Vibration at highway speeds (55-70 mph)
Clicking sound when shifting from Drive to Reverse
Visible rust or play in U-joint when inspected
Driveshaft vibration felt through floor of truck
How to Fix
Replace the U-joints with heavy-duty aftermarket units rated for towing. Spicer Life Series 5-1350X or 5-760X are popular upgrades. Replace both driveshaft U-joints at the same time. Grease the new U-joints immediately after installation and at every oil change interval thereafter. If the driveshaft yoke ears are worn, the driveshaft must be replaced. Budget $200-$600 for parts and labor.
Owner tips & cautions
TipSpicer Life Series U-joints (5-1350X or 5-760X) are the go-to upgrade for towing. They are stronger than OEM and have greaseable fittings. Grease at every oil change.
WarningDo not ignore U-joint clunking — a failed U-joint can cause the driveshaft to drop at highway speed, which can vault the truck or damage the road. This is a safety-critical repair.
On the 2010-2025 RAM 2500, the BorgWarner BW4470 (part-time 4WD) and BW4494 (full-time 4WD) transfer cases develop fluid leaks at the front and rear output shaft seals and at the case halves. The leaks are often slow and go unnoticed until the fluid level drops enough to cause whine, grinding, or failure to engage 4WD. Trucks used for towing are more susceptible due to higher operating temperatures.
Low fluid level on transfer case dipstick or fill plug
How to Fix
Replace the leaking output shaft seal(s). If the leak is at the case half, reseal with Mopar RTV sealant during reassembly. Refill with the correct fluid: Mopar 05166184AA (BW4470) or equivalent ATF+4 (BW4494). Check fluid level at every oil change, especially on trucks used for towing. Seal replacement runs $200-$500 depending on which seal.

Owner tips & cautions
TipAdd a magnetic drain plug when servicing the transfer case — it catches metal shavings before they circulate and cause wear. Check fluid level at every oil change.
TipIf your truck tows regularly, change the transfer case fluid every 30,000 miles instead of the factory 60,000-mile interval. Heat from towing breaks down the fluid much faster.
On the 2003-2018 RAM 2500, the American Axle (AAM) front differential on Ram 2500/3500 4x4 trucks is well known for recurring front pinion seal leaks. The pinion seal rides on a sleeve/wear surface on the pinion flange; over time the seal wears a groove into the sleeve, so simply installing a new seal on a grooved sleeve leaks again quickly. Owners on Cummins/Ram forums report going through multiple pinion seals. The same trucks also commonly leak at the axle-tube input/output shaft seals. Left unaddressed, gear oil coats the front driveshaft/underbody and the differential can run low on lubricant.
Common Symptoms
Gear oil leak at front pinion/driveshaft flange
Oil film on front driveshaft and underbody
Low front differential fluid
Repeat leaks after a seal-only replacement
Gear-oil smell
How to Fix
Replace the front pinion seal AND the pinion flange sleeve (wear sleeve) together, not the seal alone, since a grooved sleeve will re-leak. Set pinion preload correctly on reassembly. Inspect the axle-tube/input shaft seals at the same time and replace if seeping. Use the correct gear oil and confirm the axle vent is not clogged (a plugged vent builds pressure and pushes oil past seals).

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the EGR cooler routes hot exhaust through a coolant-jacketed heat exchanger before recirculating it into the intake. Heavy soot loading progressively plugs the cooler and EGR valve, first showing as slight off-idle hesitation and rising EGTs, then triggering EGR flow/performance codes and limp mode. Worse, a clogged, thermally stressed cooler can crack internally and leak coolant into the exhaust/intake stream, causing white smoke, coolant loss, and potential hydrolock or catastrophic engine damage. Cummins service intervals call for cleaning the EGR valve/cooler roughly every 67,500 miles (2007.5-2018) or 75,000 miles (2019+), which many owners never perform.
Clean or replace the EGR cooler and valve. Genuine replacement cooler OEM PNs include 68048988AA (and related 4988885 / 4988884 / 68048991AA / 68444764AA for later trucks); an upgraded H-core cooler (e.g., BulletProof Diesel) resists cracking and clogging better than stock. Replace the EGR valve if the pintle is coked. Keep the DPF/regen system healthy, avoid excessive short-trip idling, and inspect/clean on Cummins' recommended interval to prevent the crack-and-coolant-loss failure mode.

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the 68RFE 6-speed automatic behind the Cummins is prone to torque converter shudder and lockup failure. The factory converter's clutch material and heat control are marginal for the Cummins' torque, so the torque converter clutch (TCC) chatters, slips, or refuses to hold lockup, felt as a low-speed vibration like driving over rumble strips. The TCC regulator valve wears its bore in the valve body, making apply pressure erratic. The resulting heat contaminates the fluid and cascades into planetary and clutch-pack damage. Heat is the number-one killer, especially when towing; fluid temps regularly over 200°F accelerate failure.
Shudder/vibration around 40-55 mph (converter lockup)
Slipping or flaring on lockup
High transmission temperatures when towing
Harsh or delayed shifts
Burnt-smelling ATF+4 fluid
Check engine light with TCC codes
How to Fix
Replace the torque converter with a stronger billet/multi-disc unit (e.g., Sun Coast, BD Diesel, or Suncoast triple-disc) rather than another stock converter. Rebuild or upgrade the valve body / TCC regulator valve (Sonnax) to restore correct apply pressure. Add an auxiliary transmission cooler and use the correct ATF+4 fluid, and consider a deep pan and improved fluid capacity for towing. Address early to avoid a full transmission rebuild.

On the 2013-2018 RAM 2500 6.7L Cummins Turbo Diesel, the concentric (belt-driven) water pump on 6.7L Cummins trucks can leak coolant and suffer bearing failure. NHTSA recall 17V562000 covered 2013-2017 Ram 2500/3500 and cab-chassis trucks whose water pump lacked a vent hole, allowing coolant to leak onto hot engine components and create a fire risk. Separately, owners report the pump bearing seizing and throwing the serpentine belt, one at just 32,000 miles while towing, leaving the truck without cooling or charging. Symptoms include coolant weeping from the weep hole, whining/grinding from the pump, and overheating.
Check the VIN against recall 17V562000 (repair is free at a Ram dealer for affected trucks). For out-of-warranty failures, replace with the updated vented water pump (Cummins service PN 5473057 supersedes earlier numbers) and inspect the serpentine belt, tensioner, and fan hub while access is open. Address any coolant weeping promptly to avoid belt loss and overheating.

On the 2014-2018 RAM 2500, heavy-duty 2014-2018 RAM 2500 pickups delivered with a Kidde plastic-handle or push-button 'Pindicator' fire extinguisher fall under NHTSA recall 17V824000. Kidde found that these extinguishers can clog internally. A clogged unit either fails to discharge at all or takes excessive force to set off — neither is acceptable in the seconds an owner has to act. Separately, certain Kidde models can throw the nozzle off the valve assembly with enough force to injure whoever is holding it, and the extinguisher is then useless. Nothing on the RAM 2500 itself is defective; the recall follows the extinguisher that shipped with the truck, so it applies even if that extinguisher has since been moved to the toolbox or under a rear seat. The full list of covered Kidde model numbers is published by NHTSA at https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf.
Common Symptoms
Extinguisher does not discharge when activated
Handle or button requires excessive force to operate
Nozzle blows off the valve assembly during use
How to Fix
Replacement is free of charge and is handled by Kidde, not by a RAM dealer repair. Chrysler's notification instructs owners to contact Kidde for a free replacement extinguisher — Kidde at 1-855-262-3540 or www.kidde.com under 'Product Safety Recall'. Chrysler customer service is 1-800-853-1403; the manufacturer's recall number is T82 and owner notification began February 14, 2018. Run your VIN through nhtsa.gov/recalls to see whether your 2500 is on the campaign, then match your extinguisher's model number against the NHTSA list. Keep a working extinguisher in the truck in the meantime rather than relying on the recalled unit.
On the 2014-2022 RAM 2500, the center high-mounted third brake light on RAM 2500 trucks is a chronic water-leak point across both the 4th (2010-2018) and 5th (2019+) generations. The thin foam gasket sealing the lamp housing to the cab roof compresses, dries out and degrades, letting rainwater pass through the mounting holes into the cab sheet metal. Because of how the roof slopes, water runs down and shows up as staining on the headliner in the rear corners above the back glass. Beyond cosmetic damage, water frequently drips onto interior electronics — owners report soaked and corroded Body Control Modules (BCM) and other connectors, escalating a cheap seal failure into an expensive electrical fault.
Common Symptoms
Water stains on headliner in rear corners
Dripping water inside cab after rain/wash
Wet rear seat or floor
Musty smell
Electrical gremlins / BCM faults from water intrusion
How to Fix
Remove the third brake light (typically two Phillips screws), reseal or replace the degraded foam gasket with a fresh thicker gasket, and apply butyl/RTV sealant around the mounting studs; replace the lamp assembly if cracked. Dry the headliner and inspect/dry the BCM and connectors. If water reached the BCM, cleaning or module replacement plus reprogramming may be required.

On the 2010-2025 RAM 2500 6.7L Cummins, the cast iron exhaust manifold on the 6.7L Cummins turbo diesel cracks due to thermal cycling stress, particularly near the center cylinders (#3 and #4). Cracks allow exhaust gases to escape, creating a ticking noise on cold start that diminishes as the manifold expands when warm. Exhaust leaks can also send soot into the engine bay and affect turbocharger performance by reducing exhaust backpressure to the turbine.
Ticking or tapping noise on cold start that fades when warm
Exhaust soot or staining on engine bay components
Slight exhaust smell in engine compartment
Reduced turbo boost in severe cases
Visible crack on manifold surface upon inspection
How to Fix
Replace the cracked exhaust manifold. OEM replacement (Mopar 68408593AA) or aftermarket upgraded manifolds from BD Diesel or Industrial Injection are available. Aftermarket options are typically thicker castings less prone to re-cracking. Always replace the exhaust manifold gaskets and inspect/replace any stretched or corroded manifold studs. Budget $600-$1,500 for parts and labor.

Owner tips & cautions
TipBD Diesel and Industrial Injection make thicker aftermarket manifolds that resist cracking better than OEM. Worth the upgrade if the factory manifold has already cracked once.
WarningAlways inspect manifold studs during replacement — corroded or stretched studs will snap during removal. Have an extractor set and replacement studs on hand before starting the job.
On the 2010-2018 RAM 2500, the HVAC blend-door actuators behind the RAM 2500 dash use small plastic gears that strip over time. When the gear teeth fail, the actuator motor repeatedly tries and fails to move the blend door, producing a persistent clicking/knocking noise from behind the dash and loss of temperature control — commonly one side of the cab blows hot while the other blows cold, or the system won't switch between heat and AC. In some cases the fault is not the actuator but the HVAC control module driving it (owners report good actuators mis-operating in a given socket), which requires a different repair path.
Common Symptoms
Repetitive clicking/knocking behind dashboard
One side of cab warmer/cooler than the other
No heat or no AC despite correct settings
Air won't change between vents/modes
Clicking that changes with temperature adjustment
How to Fix
First attempt the actuator recalibration procedure (cycle key / hold the recirculation button until the LED flashes) so the actuators re-learn their end stops. If clicking persists, replace the failed blend-door actuator(s); the parts are inexpensive but several are buried deep behind the dash, and dual-zone systems can require pulling the dash (8+ hours). If a new actuator still misbehaves, the HVAC control head/module is replaced instead. Note aftermarket actuators are weaker than OEM and may fail early.
