On the 1995-2006 GMC Suburban, the GMC Suburban (and Chevrolet Suburban/Tahoe/Yukon) with rear AC systems develop leaks in the rear evaporator core and the aluminum rear AC lines that run along the passenger-side frame rail. The lines corrode under the securing straps from road salt and moisture. The rear drain tube also clogs, causing musty odors inside the cabin. Repair is costly because the rear AC system is difficult to access.
Confirm the leak by recovering the refrigerant, pulling the system into vacuum, and pressure-testing with dry nitrogen and UV dye or an electronic leak detector at the rear evaporator case and the aluminum lines running along the passenger-side frame rail, especially under the retaining clamps. Replace any corroded rear lines and, if leaking, the rear evaporator core and O-rings, then flush debris, evacuate the system, recharge to factory specification, and clear the rear evaporator drain tube to stop water intrusion and mildew odor. Many owners in rust-belt areas choose a rear A/C line delete or block-off kit if rear cooling is not needed, which is cheaper than full line replacement. Typical cost is about $400-$900 for line repair/delete, or roughly $1,200-$2,000+ if the rear evaporator core and interior trim access labor are required.

On the 1992-1999 GMC Suburban, the rear heating and A/C system suffers from blower motor failure and rear heater core leaks. The rear heater core is located under the rear cargo area and is susceptible to coolant corrosion.
Replace rear blower motor (VDO PM3542) and/or rear heater core. The rear heater core requires removal of rear cargo panels for access. Flush the cooling system and use proper coolant mix to prevent future corrosion.
