I know a thing or two about cars, but I can't figure out why the cooling fan isn't coming on. I've swapped the fan relay, checked the fan fuse, checked the fan itself, swapped the temp sensor. What else is there to check. My guesses are its the PCM (computer) or a faulty wire somewhere, but those would be extremely hard to diagnose and I don't want to pay for a new PCM. Does anyone have any guesses as to what else it may be?
