Fig. 2.50. Wiring diagram of the cooling system fan control
Unlike the previous electric fan system, the coolant temperature sensor switch has been removed. Instead, a coolant temperature sensor is used to control the fan's electric motor, which simplified the system. The cooling system fan control system switches on / off 3 fan relays according to the coolant temperature and the operating mode of the air conditioning system. When the fans are turned on, the two electric fan motors can operate at low power (consistently) or high (parallel) speed.
