Sometime my radiator fan switch works fine and sometimes not at all.
I have had overheating problems. I think I have narrowed to problem down to
the radiator fan switch. Yesterday I drove the car all afternoon and got home ,
parked with engine running and no overheating. The fans clicked on and off
like they are supposed to. Today I went out and started cold engine and let
warm up good. No fans today and my engine started to overheat. Fans work
fine and switch works fine when it's working. What else could cause this if it
still happens after I replace fan switch? Thanks
