The odor usually occurs within 20 to 60 seconds after the vehicle is started. Condensation, which is a normal condition in all A/C systems, can cause a musty odor. If the odor is noticeable in the vehicle when the engine is not turned on, the cause may be mold and mildew in the passenger compartment, and not be related to the A/C system. All other possible sources of the odor must be investigated before this bulletin can be performed. |
