June 10, 201015 yr Hi guys/gals, Can someone tell me if my electric cooling fan on the radiator has a relay and where I can find it. This is on my 93 loyale wgn. Any help would be greatly appreciated.
June 10, 201015 yr The system is really simple.There is no relay,just a Thermo Switch on the radiator.It's a two wire,screw in type switch that is in one of the bungs on the passenger side radiator tank. When the coolant reached a certain temp,the switch closes and the fan comes on. If your fan isn't working,aside from checking the wire condition and the grounds,take a look at that switch. There is a test proceedure for the switch,I don't know what it is.
June 10, 201015 yr Author I thought that there was a A/C relay that turns the fan on automatically when the A/C is turned on besides the thermo switch??? Can someone set me straight about this???
June 11, 201015 yr Should be two relays on the passenger side strut tower. One for the fan and the other for the AC. Just swap them and see what happens.
