I'm having climate control issues on my 92 GT, when the ignition is in the run position, but the engine is off, no matter what setting I put the air on the defroster blows, none of the other vents will work. If I turn the engine on nothing works, not even the defroster. Then I noticed while driving that my turn signals weren't working either, I have a new multifunction switch so I think the turn signals not working has something to do wit the ac problem. I've checked all the fuses, they're all fine, and I disconnected the battery to try resetting a sensor maybe and after I reconnected it everything worked fine, but when I started the car up later, I had the same problems. Any ideas??
