B0414 on Chevrolet
Manufacturer-Specific Body Code (GM: A/C Air Temperature Left Feedback Circuit Actuator Range/Performance)
B0414 on Chevrolet vehicles indicates manufacturer-specific body code (gm: a/c air temperature left feedback circuit actuator range/performance). Au7o has documented this code across 2 Chevrolet models — most commonly on Equinox, Silverado 1500. B0414 is a body code most common on GM vehicles, indicating a range/performance problem with the left-side (driver) automatic climate-control temperature blend-door actuator feedback circuit. The HVAC control module commands the blend-door actuator and reads its position feedback; this code sets when the reported position doesn't match the commanded position or is out of range. Symptoms are usually limited to incorrect or uneven cabin temperature on the left side, sometimes with clicking from behind the dash. It is a comfort-system issue rather than a safety concern. The exact definition should be confirmed against the specific vehicle. Typical repair costs on Chevrolet range from $100 to $900, depending on the specific model and root cause.
Common Causes of B0414
- •Faulty left temperature blend-door actuator
- •Binding, broken, or stuck blend door
- •Wiring or connector fault in the actuator feedback circuit
- •Worn actuator position-feedback contacts
- •Stripped actuator or door gears
- •Poor ground or low voltage to the actuator
- •Faulty HVAC control module
B0414 on Chevrolet by Model
Chevrolet Equinox(1 issue)
- HVAC Blend Door Actuator Failure Causing Clicking Noise and Incorrect Temperature/Airflow2005-2009
A common first-generation Equinox/Torrent problem is failure of one or more HVAC door actuators, especially the temperature blend and mode actuators. Owners report repetitive clicking or knocking from behind the dash, inability to switch between defrost/floor/panel modes, or heat stuck hot/cold on one side. GM service information and owner reports point to stripped plastic gears or an actuator that loses calibration after battery disconnect or normal wear.
Chevrolet Silverado 1500(1 issue)
- Blend Door / HVAC Actuator Failure Causing Clicking Dash Noise and Incorrect Airflow Temperature2000-2013
A frequent Silverado complaint is failure of the HVAC mode or blend door actuators, which causes repetitive clicking from behind the dash and leaves the system stuck on one vent mode or one temperature setting. Owners often notice one side blowing hot while the other stays cold, air stuck on defrost, or recirculation not functioning correctly. The small plastic gears inside the actuators wear or strip, and recalibration may not restore operation once gear damage occurs.
