Maybe faulty temp sensor, relay or fan motor. Come on with AC? Do you have a volt meter and some understanding of electronics?

No I don't but I can probably get one. And no I'm not very good on electrical. I bought a cooling fan relay for $5 but it won't be available until tomorrow am I on the right track?

I would really be surprised if what you're getting even fits the car. 2 out of 3 of these relays are 5 wire relays and not your generic style. It's a 2 speed system so if you have a bad relay somewhere, chances are you'd have at least one speed working. Check all your fuses carefully and that's about as far as you'll be able to go yourself.

Hey SISCO707,

I found a better wiring diagram for you it looks like the problem could be one of the relays or one of the two fuses, make sure you check them all, here are a couple of guides that can help you.
