Air Deliver| (cont'd)
- How the Circuit Works
The air delivery system directs the flow of air used
by the heater and air conditioner systems.
Mode Selection
Mode selection is controlled by the mode switches in
the heater control panel and the mode control motor.
When you select a specific mode, voltage is applied
through the dimming control circuit to the LED, which
comes on, indicating the mode selected. Ground is
provided to the mode control motor though that
mode switch. The motor then runs until the air
control door reaches the proper position.
Fresh/Recirculation Selection
When you press the recirculation button, a ground
signal is sent from the heater control panel to the
recirculation control motor. The motor lhen runs
until the recirculation door reaches the opposite
Dosition. When the recirculation button is in the
REC position, battery voltage is applied through the
dimming control circuit to the recirculate LED, and
the LED comes on.
Refer to the Service Manual (Section 21, Heate0 for
specif ic tests or troubleshooting procedures.

A/C Gompressor Controls (conrd)
- How the Circuit Works
Battery voltage is supplied through fuse 56 to the
A,/C compressor clutch relay contacts at all times.
With the ignition switch in ON (ll), voltage is applied
to the coil of the A,/C compressor clutch relay
through fuse 17. When you push the A,/C switch
ON, and the heater fan switch is in posation 1, 2, 3,
or 4, a "ground" input is provided to the engine or
powertrain control module (ECM or PCM) through
the A,/C thermostat and the A,/C pressure switch.
The A,/C compressor clutch relay is grounded by the
engine or powertrain control module (ECM or PCM).
When energized, the A,/C compressor clutch relay
allows battery voltage to turn on the A,/C
comDressor clutch,
The A,/C ON indicator light comes on when the A"/C
system is requested.
A,/C Thermostat
The A,/C thermostat is located on the evaoorator
housing. The AJC thermostat turns off the A,/C
compressor clutch if the temperature at the
evaporator goes below 3'C (37'F). This prevents
condensation from freezing on the evaporator fins
and blocking the air delivery into the passenger
compartment. The blower motor will keep running
when the sensor lurns off the compressor.
A,/C Pressure Switch
The A,/C pressure switch is located in the condenser
outlet line where refrigerant is in a high
temperature/high pressure liquid state. The switch
will sense abnormally high or low pressure, and
open the circuit. This removes ground, and the
compressor will stop running.
Refer to the Service Manual (Section 22,
Air Conditioning) for specific tests or
troubleshooting procedures.
