Odor Description

Odors may be emitted from the air conditioning system primarily at start up in hot, humid climates. The odor may be the result of debris in the HVAC module or the growth of mold on the evaporator core. To address this condition, a service kit is available through GM SPO.

A single application of deodorizer GM P/N 12370470 will remove odor from the air conditioning system. Installation of a delayed blower control module is recommended to prevent the odor from returning. Should the delayed blower control module be used, refer to the installation instructions that come with the part.
