Mirage 1.6L
- With A/C on Low, 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.
- 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. See Figure .
- If pressure switch is activated by excessive pressure or if thermosensor is on when engine coolant temperature exceeds 185°F (85°C), this activates condenser fan motor control relay. This causes condenser fan and radiator cooling fan to operate at a high speed.
