A/C HEATER CONTROL MODULE
DESCRIPTION
The manual temperature control HVAC system uses a
combination of electrical, and vacuum controls. 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 sug-
gested operation and use of these controls.
Both A/C heater control module panels are located on
the instrument panel inboard of the steering column
and above the radio. The A/C heater control panel
contains two rotary-type temperature control knobs (2
and 5), a rotary-type mode control switch knob (1), a
rotary-type blower motor speed switch knob (6) and
an air conditioning compressor push button switch (3).
OPERATION
Dual zone temperature control provides a side-to-side variation in comfort temperatures to exceed the needs of
either front seat occupant.
The A/C Heater Control Module panels are serviced only as complete units and cannot be repaired. If faulty or
damaged, the entire A/C Heater Control Module must be replaced.
The A/C Heater Control Module makes it possible to make adjustments coming from the driver such as:
•
“Temperature” by setting the temperature thumb-
wheels. (2 and 5)
•
“Air quantity” by adjusting the blower switch set-
ting. (6)
•
“Air distribution” by setting the air distribution
switch. (1)
•
“Recirculating air” by pressing the recirculating
air push-button. (4)
•
Activating the residual engine heat utilization sys-
tem with the ignition switched off by pressing the
REST button. (4)
•
Switching off the A/C by pressing the EC button
(3).
The A/C Heater Control Module integrated in the push-button control module looks after all system regulation and
control functions, such as:
•
Automatic switchover from fresh air to recirculated air mode.
•
Electrical control of the A/C compressor.
•
Control of the electric fan for the engine/air conditioning system.
