SUBJECT:
Air Conditioning System Odor / Afterblow Function
REFERENCE:
VIDA
DESCRIPTION:
There may be cases of odor from climate system vents on the vehicles listed above. Ensure the odor is not from some other source and all other A/C system checks have been completed. If necessary the Afterblow function can be activated to dry out the ventilation system and evaporator. There are two ways to activate the Afterblow function depending on the Model Year (MY). For MYs 2005 and later and for MYs 1999 - 2004 refer to image above.
NOTE:
Up through 2002 Afterblow was activated from the factory, 2003 and later Afterblow will be Retailer activated only.
SERVICE:
In all cases basic fault tracing needs to be performed prior to the afterblow activation. Once this has been completed see the appropriate instructions for Afterblow activation.
Check / Verify that:
- There are no refrigerant leakages (not PAG oil causing the odor).
- AC drain is not clogged - drains sufficiently i.e. no water standing in the climate box.
- No water standing underneath the floor carpets.
- Cabin air filter inspected / verify it's been replaced according to the maintenance schedule.
- Battery is in good condition.
If all the above has been checked and confirmed that they are not the cause of the odor then the Afterblow function should be activated to minimize the risk of odor.
NOTE:
MY 2005 and later it is only necessary to activate / deactivate Afterblow one time per vehicle. If ANY new software is downloaded the Afterblow function will stay activated.
