Odor Diagnosis

A/C Odor Diagnosis:

Odors may be emitted from the air conditioning system primarily at start-up in hot, humid climates. This odor may be the result of debris in the heater / evaporator case or growth of mold on the evaporator core. To address this condition, a service kit is available through GMSPO.

CAUTION: Procedure should only be performed on a cold vehicle to prevent the disinfectant from coming in contact with hot engine components. Disinfectant can cause substantial but temporary eye injury. Do not get in eyes or clothing. Wash thoroughly with soap and water after handling.
