HVAC Odor Maintenance
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.
NOTE
The procedure in this bulletin will NOT eliminate the odors described but is provided to help reduce
intensity of the odors.
1. Confirm the condition exists.

outside influences, such as debris, this
bulletin may NOT be effective in reducing
the odors.

HVAC Odor Maintenance
General Procedure (continued)
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 the Parts Information section for the correct part).
4. If the odor condition persists, conduct an A/C evaporator cleaning service using a
Toyota genuine A/C refresher kit (or equivalent) on an annual or bi-annual basis,
depending on the climate conditions and customer preference.
NOTE
If the A/C evaporator cleaning service is NOT performed before installation of the high-performance
filter, the filter may take several days to produce noticeable A/C odor improvement.
