| Condition |
Some customers may comment on an odor from the HVAC system when the engine is at operating temperature and the instrument panel temperature control set on the full heat setting. |
| Cause |
This condition may be caused by the grease used to lubricate the components inside the heater and air-conditioning evaporator case. |
CORRECTION
Bring the vehicle up to operating temperature and verify the condition by closing the vehicle doors, idling the car and selecting full heat.
- You may wish to let vehicle idle for several minutes with heat on high, open the driver door and verify the concern.
- Follow the latest version of PI0740 and Odor Diagnosis in SI to ensure that the odor is not coolant, as described in SI.
SERVICE PROCEDURE
TIP:
Using a digital camera, photograph the routing of the instrument panel wiring harness before removal. This will aid in the re-assembly process.
- With the condition verified, replace the heater and air conditioning evaporator case. Refer to Heater and Air Conditioning Evaporator Case Replacement
in SI.
- With the heater core removed from the case, inspect for contamination from the assembly grease. Clean as necessary.
- Transfer the following items from the old assembly:
- Floor air outlet cover
