I have a '96 supercharged. Has the automatic climate control. When I bought it the seller told me that the AC was fine, except there was "some sort of switch that needs to be replaced under the dash". I took the car to my mechanic and he told me that the AC system was completely empty of freon. However, it doesn't blow any cold air at all, in fact it is as hot as I think it can get. I'm pretty sure its the Temperature Actuator Valve and I know where it is. Does anyone have a picture of what this valve looks like or know the gm or ac delco part number for this thing?
