For some reason my electric fan will not work when the engine gets hot. I checked the inline fuse and I replaced it just to be safe. If I want the fan to turn on I have to use the switch to get it to work. I also turned the temperature control on the relay all the way down. I think the A/C relay might be fried. Anyone have any pointers??

 

Is this a new install or has it worked before?

Does it click on when you flip on the A/C?

 

My fan went dead once and it turned out to be a 30 amp fuse in the wiring from the fan to fuse box.

D-Day

 

What kind of fan is it?
