AC went out....Help!!

[jcase350]

I have a 90 Camaro Iroc-z w/350. The AC went out on me today. It is not blowing any air at all...heat or AC. Are there any relays or anything else i need to check before i replace the blower motor? Thanks in advance!!

Have you tried running the fan on all speeds?

There is a a reisitor relay that regulates the speed of the fan, if it works on high only, than the relay is porbably toasted.

If it's not working at all, then there's the fuse or the motor it'self.

Can u tell me where the resistor relay is at....i see a relay next to the motor...is that the one you are talking about? Also....today i got in my car and the AC worked....got a haircut...went back out to the car and the AC was back to not working again. I don't get it!!

I'm really not sure, might be, shouldn't be too far away, trace the wiring from the fan.

Thought you guys might wanna know what happened. After some troubleshooting I found out the blower motor went out. Weird thing is it would come on every once in a while like nothin was wrong. Weird!! Thanks guys!
