Cooling Fan Will Not Turn On

Hi all.



I have a car that is overheating and for some reason the cooling fan is not turning on. I have replaced the fan's motor, the relays and the temperature sensor but it still will not turn on. I have a 1994 Pontiac Grand Am, 4 cylinder. Before all this happened I got the low coolant or that engine light that says it is too hot. Tonight, I replaced the the temperature sensor and when I went for a drive it still was starting to go hot and I got the Service Engine Soon indicator light. Is there something else that I need to replace on this car? I am not leaking any fluids here that I can see. I don't have a lot of money either so what else is needed here? My car is pretty much my livelihood so it is hard to live without it.

The engine fan from what I understand of the GMs of that age is that it'll have an engine fan controlled by your ECM. Check your computer wiring and report back.

If all else fails run a 12V line from your battery to the fan and put a simple switch on it. :-P

Nick.

It could be a blown headgasket ... those damn 4 bangers were prone to it.

Where would I find the headgasket on my car?

It's under the head :P Do you have milky colored oil? Does the exhaust have foggie looking air coming out of it?

I do not know. I never looked to see if I had smoky exhaust or not. I took it into the mechanic today. I think this thing might be electrical because of the way it is acting after we put those parts in.
