I've been noticing that my car has a tendency to overheat for some time (a few months maybe). I finally investigated it and found out that my cooling fan wasn't coming on, even though the car was clearly getting hot. I went through the electrical schematics, and figured out that the temperature switch (the one that plugs into the bottom of the radiator) was the problem. I bought a third-party switch, and replaced my old one, and I noticed that now my fans were coming on, but only when the gauge was just about in the red. I went back to the store and exchanged it for another one, and this time the fans didn't switch on even when the gague went into the red. I was told that for this part, this sort of thing can happen, and the only replacement switch that will work is one I get from the Toyota dealership. Has anybody dealt with this situation before? The car is a '95 Camry, 4 cylinder 2.2 L engine.
Thanks
