Musty Smell of Coolant Smell
| • | Check for water leaks. Seal the body as necessary. |
| • | Check the evaporator drain for blockage. Remove blockage. |
| • | Check the coolant level. If it is low inspect the heater core or heater pipes/hoses. |
Under certain climate and operating conditions, a musty odor develops from mold growth in the evaporator core face. This odor is generally temporary. As climate conditions change, the condition will repair on its own. However, if the odor persists, remove the evaporator core and clean the face with an appropriate cleaner.
Odors may be emitted from the air conditioning system primarily at startup in hot, humid climates. This odor may be the result of debris in the heater/A/C evaporator case or growth of mold on the Evaporator core.
