HEATER AND AIR CONDITIONING
GENERAL DESCRIPTION
The circuit consists of the pressure switch, NC switch, electric thermostat, blower motor, fan switch, magnet
clutch of the NC compressor, blower resistor and relay.
The start and stop of the NC is controlled by turning the NC switch on and off. The electric thermostat and the
ECM can stop the operation of the NC temporarily by disconnecting the magnet clutch under the
predetermined conditions
to adjust the room temperature, preventing the abnormal rise of the engine coolant
and reduce the engine load while the NC is in operation.
Refer
to Section 18 "AIR CONDITIONING" for detail.

SUN ROOF
GENERAL DESCRIPTION
The circuit consists of the starter switch, sun roof switch, sun roof control unit, safety stop switch, limit switch,
and sun roof motor.
When the sun
roof switch is turned on, the battery voltage is applied to the sun roof control unit through the
circuit breaker and the power
window relay on the circuit.
Accordingly,
when the sun roof switch is set to "Open" or "Close" position, the open or close relay incorporated
into the control
unit is activated to change the rotational direction of the sun roof motor to open or close the
sun roof.
Also, the operational process (full close-> limit stop-> full open-> safety stop-> full close) ofthe sun roof
is
controlled by the control unit in accordance with signals received from the safety stop switch and limit switch.
OPERATION OF SUN ROOF
