My fan on my 1986 z28 won't come on!! almost everything works and I know the problem is the fan switch on the pass. side head but I can't find what everyone calls the "fan switch", there are no wires or a sensor anywhere in the pass. side head. I decided to either wire the fan up to a switch or to something that will turn it on when I start the car. I'd like to wire the fan to something that has power at all times when the car is running. Anyone have any ideals??

 

I put the fan switch in the water pump it work very well

 

I hope this help
