Some vehicles may experience odors 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 and evaporator module or microbial growth on the evaporator core.

A single application of the Goodwrench Air Conditioning System Deodorizer will remove odor from the air conditioning system. However, the afterblow option should be enabled to prevent this condition from recurring. The afterblow option can be enabled by the scan tool.
