fans arent coming on Ok i just bought this 93 camaro and the heads were cracked and radiator busted and clutch was shot well i finally got it back together over spring break and the fans would not come on, right now they are just hardwired in. I have replaced all the relays, temp switch, and the coolant temp sensor. Only thing I can think of is that it is a bad wire or a computer problem. What do you guys think?

Not always my friend I had a O2 that was bad and was stopping my fans from turning on. if you look at the wiring diagram you will see they run off the same circut
I also have a 93 and mine did the same thing. I replaced everything and it wouldnt ever come on. The care would be overheating and still no fans. How do you get the codes reset. Because i even changed the computer and still no luck

wow thats crazy whats up w/ all the 93 having this problem. i have it to but im not worried about it i kinda like the way i have it setup right now. i just wired it to the ign and it turns on and stays runing with the key. so after i give it a couple runs down the track i could cool the car down just by turning the ign. on

Now for you: If a code follows you through computer swaps, then it's a sure sign of the problem not being fixed (whatever the code is for).

You have a 93, so this doesn't really pertain to you, but newer PCMs I believe can write codes to a more permanent memory that will persist through power loss. Those don't trip an SES though, since they're just stored.
