I was having an issue where my front a/c would only blow at high speeds, then it went out completely. I read that changing the resistor would help, so I replaced it, but it didn't fix the isssue. Neither did replacing the blower. I replaced both and now it'll blow, but it's stuck in high speed and won't shut off even after I turn the engine off. It's odd because the same **** controls the rear a/c and it does just fine. Any ideas?

 

Welcome from Florida. You might have a stuck relay for the blower motor. Try changing them around only with another one one with the same part number. If the problem moves to the other location you have a bad relay.
