Cooling Fan

Hey Guys,

I have a 1994 stock Pontiac Firebird Formula and the cooling fan is not coming on at the proper temperature. I have replaced all three relays and when I did that, the fan came on. The next time I started the car, the fan did not come on. Any solutions or suggestions to diagnose the problem will be appreciated.

Thanks!

I believe it is 200 or 210, but the main thing is the fan is not coming on at all anymore. Any Help will be appreciated.

Thanks!!

If you had looked at the links Rob/Shoebox posted, you would have found that the 1st fan (or high speed on later models) comes on at 226*F and the 2nd fan (or high speed) at 235*F. Did you work your way through his checks in the links?
