Stupid Fan Problems

Hi Guys,

I am having issues with my fan. I have taken my car into Ford previously to get the breaker installed.

I was driving home yesterday and noticed that my car was running hot. Popped the hood, turned on the A/C to Max and the fan did not turn on.

I just took off the breaker and plugged the fan in. I started the car and turned on the A/C to Max and voila! the fan turned on. However, is the fan supposed to stay on all the time if the A/C is on, or is it intermittent? I noticed that my fan turns on and off while the A/C is on and was wondering if that is normal.

-----------------------
Well...I checked out my friends stang and his fan stays on all the time while the A/C is on Max. Any ideas as to what would cause my fan to turn on and off? Wondering if the fan is semi-seizing? Any ideas?

Thanks!

Thanks for the input Hissin50.

Yeah, I'm not planning on running the car without the fan breaker, it was just a test to see if the breaker was bad.

I'd prefer to not put a manual switch in if I don't have to. So where would the fan switching hysteresis be controlled?

Thanks again!
