MIRAGE 1.5L
- With A/C on "Low" and ignition on with engine coolant temperature greater than 185°F (85°C), thermosensor completes the ground. This closes the contacts on radiator fan motor relay and provides current to the radiator fan motor.
- With A/C on "High" and ignition on, power supply from auto compressor control unit causes condenser fan motor relay and condenser fan motor control relay to turn on. This causes condenser fan and radiator cooling fan to operate. (Scheme 1)

MIRAGE 1.6L
- With A/C on "Low" and ignition on with engine coolant temperature greater than 185°F (85°C), thermosensor completes the ground. This closes the contacts on radiator fan motor relay and provides current to the radiator fan motor.
- With A/C on "High" and ignition on, power supply from auto compressor control unit causes condenser fan motor relay to turn on. This causes condenser fan and radiator cooling fan to operate at a low speed by usage of a resistor. (Scheme 2)
- If pressure switch is activated by excessive pressure or if thermosensor is on when engine coolant temperature exceeds 185°F (85°C), this activates the condenser fan motor control relay. This causes condenser fan and radiator cooling fan to operate at a high speed.
Scheme 2
GALANT & SIGMA
With ignition on and engine coolant temperature greater than 194°F (90°C) on Sigma or 185°F (85°C) on all others, thermosensor completes the ground. This closes the contacts on radiator fan motor relay and provides current to the radiator fan. (Scheme 3)and (Scheme 4).

STARION
- With ignition on and engine coolant temperature greater than 185°F (85°C), thermosensor No. 1 completes the ground. This closes the contacts on radiator fan motor relay No. 1 and provides current to the radiator fan motor No. 1.
- When engine coolant temperature reaches 212°F (100°C), thermosensor No. 2 completes the ground, closing the contacts on radiator fan motor relay No. 2 and provides current to the radiator fan motor No. 2. (Scheme 5)
