Passenger Compartment
Air Filter
Air Intake
The air intake in front of the
windshield in the engine
compartment must be kept clear to
allow air intake. Remove any
leaves, dirt, or snow.
Pollen Filter
The pollen filter cleans dust, pollen,
and other airborne irritants from air
entering the vehicle through the air
intake.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.
The air conditioning system requires
periodic maintenance. See
