Summit Wagon
- With A/C switch in 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.
- With A/C switch in HIGH position and ignition on, power supply from automatic compressor control unit causes condenser fan motor relay to turn on, using a resistor to cause condenser fan and radiator cooling fan to operate at low speed.
- 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 high speed.
