FAN MOTOR OPERATION
With the ignition SW turned on, the current through the ECU±IG fuse flows to the FAN NO.1 relay (Coil side), FAN NO.2 relay
(Coil side). furthermore, the current through the FAN NO.1 relay (Coil side) or the FAN NO.2 relay (Coil side) flows to
TERMINAL 3 of the A/C single pressure SW to TERMINAL 2 to TERMINAL 2 of the water temp. SW no.1 to TERMINAL 1 to
GROUND, causing the FAN NO.1 relay to turn off and the FAN NO.2 relay to turn on.
1. LOW SPEED OPERATION
When the ignition SW is turned on and the A/C system is activated, the A/C condenser fan motor and the radiator fan motor
rotates at low speed.
When the A/C system is activated, the current from MG CLT relay flows to the FAN NO.3 relay (Coil side) to GROUND,
causing the FAN NO.3 relay to turn on. As a result, the current through the CDS fuse flows to TERMINAL 2 of the A/C
condenser fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay to TERMINAL 5 to TERMINAL 5 of the FAN
NO.3 relay to TERMINAL 3 to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND.
2. HIGH SPEED OPERATION
Only when the A/C single pressure SW is turned off or the water temp. SW no.1 is turned off, the A/C condenser fan motor
and the radiator fan motor rotate at high speed.
When the A/C single pressure SW is turned off or the water temp. SW no.1 is turned off. the current from the RDI fuse flows
to the FAN NO.1 relay (Point side) to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND. At the same time,
the current from the CDS fuse flows to TERMINAL 2 of the A/C condenser fan motor to TERMINAL 1 to TERMINAL 3 of the
FAN NO.2 relay to TERMINAL 4 to GROUND.

Current always flows from the HTR fuse to TERMINAL 1 of the HTR relay. When the ignition SW is turned on, the current
from the HEATER fuse flows to TERMINAL 6 of the air vent mode control servo motor, and to the MG CLT relay (Coil side) to
TERMINAL (A) 21 of the engine control module, and to TERMINAL 1 of the A/C dual pressure SW to TERMINAL 4 to
TERMINAL (D) 10 of the engine control module, and to the HTR relay (Coil side) to TERMINAL 3 of the blower SW.
1. AIR VENT MODE CONTROL SERVO MOTOR OPERATION
When the damper is in FACE position and B/L mode on the heater control SW is selected, current flows from TERMINAL 7
of the heater control SW to TERMINAL 2 of the air vent mode control serve motor so that a signal that the ground circuit is
activated is input into TERMINAL B of the control circuit inside the air vent mode control servo motor. Simultaneously, a
signal that the ground circuit is not activated is input into TERMINAL A of the control circuit inside the servo motor. These two
signals activate the control circuit so that current flows from the HEATER fuse to the servo motor, causing the servo motor to
operate and the damper to move to B/L position. When the damper reaches B/L position. A ground cut signal is input into
TERMINAL B of the control circuit, the control circuit operates, the servo motor stops rotating and the damper stops at B/L.
When another mode position is selected, input of signals into TERMINAL A and TERMINAL B of the control circuit that
ground is made or not (as explained above) activates the control circuit and moves the serve motor to the desired position.
2. AIR CONDITIONING OPERATION
When the blower SW is on, current flows from the HEATER fuse to the HTR relay (Coil side) to TERMINAL 3 of the blower
SW to TERMINAL 1 to GROUND, activating the HTR relay. This causes current to flow from the HTR fuse to the HTR relay
(Point side) to A/C fuse to TERMINAL 2 of the A/C SW. If the A/C SW is turned on at this time, a signal is input into the
engine control module. This activates the engine control module and MG CLT relay so that current flows from the HEATER
fuse to the MG CLT relay (Point side) to A/C magnetic clutch. Causing The compressor to operate.
When blower SW is on and heater control SW is at DEF position, it causes A/C to run whether A/C SW is on or not.
