Engine Cooling Fan Relay Diagram. Theres an ac compressor clutch relay which is 44 in the same relay block which is powered by 10a ac fuse 30. It shows the components of the circuit as simplified shapes and the capacity and signal friends amongst the devices.
5 a brown 5 a beige 3 a purplethe. It uses a 40 amp electric relay and electric fan sensor. If it does not check the fuses cooling fan relays ecm and cooling fan and then check for an open circuit between the cooling fan relay and engine coolant temperature sensor.
Primary cooling fan dual fans with dual relays single speed onoff using ground switched devices only for primary activation using dual relays for two fans is not required.
This was done in my repair smog license class. The cooling fan wiring diagram below is what weve found to be the simplest and most reliable method. Often times it is no more complicated than the wiring of a well ventilated fixture. Reconnect the engine coolant temperature sensor connector.
