General Procedure
When diagnosing HVAC odors it is important to remember the following possible causes:
• During use, various odors from inside and outside the vehicle may enter into and accumulate in
the air conditioning system. These odors may then be emitted from the vents.
• Odors coming from the outside air and interior can accumulate on the evaporator. As the
evaporator core changes temperature, some of these odors may be released resulting in an
unpleasant smell from the HVAC vents.
• Interior odors from sources such as air fresheners, animals, dirt, or trash can also accumulate
within the HVAC system and contribute to unpleasant odors.
• Odors emitted from the A/C system are a normal characteristic of automotive A/C systems.
• It is normal to experience odor upon the initial startup due to the moist/humid air that is trapped
in the HVAC system, after the vehicle has been parked.

General Procedure (Continued)
NOTE
This procedure will NOT eliminate the odors experienced, but it’s provided to help reduce the
intensity of these odors.
1. Confirm the condition as described in the
introduction.
Figure 1..
If the condition is constant or is caused by outside
influences (such as debris) this bulletin may not
be effective in reducing the odors experienced.

2. Advise the customer to set the HVAC system to the outside (fresh) air mode when parking the
vehicle to assist in the reduction of odors that could be trapped in the HVAC system.
3. Replace the HVAC filter on an annual basis or every 10,000 miles with a charcoal impregnated
filter (refer to Parts Information for correct part).
4. If the condition still persists, conduct an A/C evaporator cleaning service on an annual or
bi-annual basis depending on climate conditions and customer preference.
NOTE
If the A/C evaporator cleaning service is not performed prior to the installation of the High
Performance Charcoal Filter, the filter may take several days to produce a noticeable
improvement in the A/C odor.
