WIRING SYSTEM 8D – 471
Heater and Air Conditioning
General Description
The circuit consists of pressure switch, A/C switch,
electronic thermostat, blower motor, fan switch,
magnetic clutch of A/C compressor, blower resistor
and relay.
The operation of A/C system is controlled by turning
A/C switch on and off. Electronic thermostat and PCM
can stop operation of A/C temporarily by disconnect-
ing magnetic clutch under the predetermined condi-
tions to adjust room temperature, preventing abnor-
mal rise of engine coolant and reduce engine load
while A/C is in operation.
Refer to Heating, Ventilation and Air Conditioning in
HVAC section.
