These controls provide the vehicle operator with a number of setting options to help control the climate and comfort
within the vehicle. Refer to the owner’s manual in the vehicle glove box for more information on the suggested oper-
ation and use of these controls.

3. Floor Mode Air comes from the floor
outlets. A slight amount of air
is directed through the

Description
All models are equipped with a common HVAC housing assembly that combines A/C and heating capabilities into a
single unit mounted within the passenger compartment. The HVAC housing assembly consists of three separate
housings:
•HVAC housing — The HVAC housing is mounted to the dash panel behind the instrument panel and contains
the A/C evaporator. The HVAC housing has mounting provisions for the air inlet housing, blower motor and the
air distribution housing.
• Air distribution housing — The air distribution housing is mounted to the rear of the HVAC housing and con-
tains the heater core, blend-air and mode-air doors and door linkage.
• Air inlet housing — The air inlet housing is mounted to the passenger side end of the HVAC housing. The air
inlet housing contains the recirculation-air door and actuator.
Operation
The A/C system is designed for the use of a non-CFC, R-134a refrigerant and uses an A/C evaporator to cool and
dehumidify the incoming air prior to blending it with the heated air. Temperature control determines the discharge air
temperature by operating the temperature control cable, which moves the blend-air door. This allows an almost
immediate control of the output air temperature of the system. The mode door cable operates the mode-air doors
which direct the flow of the conditioned air out the various air outlets, depending on the mode selected. When
equipped with A/C, the recirculation door actuator operates the recirculation-air door which closes off the fresh air
intake and recirculates the air already inside the vehicle. The electric recirculation door actuator and the blower motor
are connected to the vehicle electrical system by the instrument panel wire harness. The blower motor controls the
velocity of air flowing through the HVAC housing assembly by spinning the blower wheel within the HVAC housing at
the selected speed by use of the blower motor resistor, which is around the blower motor.
The air distribution housing must be removed from the HVAC housing and disassembled for service of the blend-air
and mode-air doors. The air inlet housing must be removed from the HVAC housing and disassembled for service of
the recirculation-air door. The HVAC housing must be removed from the vehicle and disassembled for service of the
A/C evaporator.

Blower Motor Electrical Troubleshooting
To determine if an open condition exists within the blower motor circuit wiring, it is necessary to disconnect the neg-
ative battery cable and check for continuity within the blower motor circuits using an ohmmeter.
Possible causes of an inoperative blower motor include the following:
•Open fuse
• Inoperative blower motor switch
• Inoperative blower motor resistor
• Inoperative blower motor
• Inoperative blower motor circuit wiring or wiring harness electrical connectors
Blower Motor Noise
To determine if the blower motor is the source of the noise, simply switch the blower motor from Off to On. To verify
that the blower motor is the source of the noise, unplug the blower motor wire harness connector and operate the
heater-A/C system. If the noise goes away, possible causes include:
•Foreign material on fresh air inlet screen
• Foreign material in blower wheel
• Foreign material in HVAC housing
• Incorrect blower motor mounting
• Deformed or damaged blower wheel
• Worn blower motor bearings or brushes
Blower Motor Vibration
Possible causes of a blower motor vibration include:
•Incorrect blower motor mounting
• Foreign material in blower wheel
• Deformed or damaged blower wheel
• Worn blower motor bearings
