General Procedure
When diagnosing HVAC odors it is important to rememberthe follo,.ving 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 NC system are a normal characteristic of automotive NC systems.
•
It is normal to experience odor upon the initial startup due to the moist/humid airthat is trapped

in the HVAC system , after the vehicle has been parked.

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.

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.
