Odor Description

The air conditioning system emits odors primarily at startup in hot, humid climates. This odor may result from the following conditions:
^ Debris in the heater/evaporator case
^ Mold growth on the evaporator core

In order to address this condition, a service kit is available through GMSPO.

A single application of this deodorizer, GM P/N 12370470, removes odor from the air conditioning system. However, installation of a delayed blower control module is recommended in order to prevent the odor from returning. Refer to the supplied installation instructions.
