ELECTRIC COOLING FAN - SYSTEM TESTING

MIRAGE 1.5L

1) With A/C on LOW position, ignition on and engine coolant

temperature greater than 185 F (85 C), thermosensor completes path to

ground, closing radiator fan motor relay contacts and providing

current to radiator fan motor. See Fig. 1.

2) With A/C on HIGH position and ignition on, power supply

from automatic compressor control unit causes condenser fan motor

relay and condenser fan motor control relay to turn on, causing

condenser fan and radiator cooling fan to operate.

MIRAGE 1.6L

1) With A/C on LOW position, ignition on and engine coolant

temperature greater than 185 F (85 C), thermosensor completes path to

ground, closing radiator fan motor relay contacts and providing

current to radiator fan motor. See Fig. 2.

2) With A/C on HIGH position and ignition on, power supply

from auto compressor control unit causes condenser fan motor relay to

turn on, causing condenser fan and radiator cooling fan to operate at

a low speed by usage of a resistor.

3) If pressure switch is activated by excessive pressure or

if thermosensor is on when engine coolant temperature exceeds 185 F

(85 C), condenser fan motor control relay is activated, causing

condenser fan and radiator cooling fan to operate at a high speed.

ECLIPSE & 3000GT

With ignition on and engine coolant temperature greater than

185 F (85 C), thermosensor completes path to ground, closing radiator

fan motor relay contacts and providing current to radiator fan. See

Figs. 7-11.
