I have a 1989 Lincoln Town Car I purchased new Septmenber 1989. It has a 5.0 engine. I'm trying to keep it in good shape. Recently I turned on the AC only to have hot air come out of the vents. The temp control is as cold as it will go. It blows " screaming hot air" on every selection. The vents, mix and defrost have the same result. The AC compressor runs when I turn on the AC or defrost and HOT air comes out even when the temp control is set to the coldest seting. I noticed the problem after I had the water pump replaced. Would there be any vacuum line near the water pump the mechanic may have knocked loose? Seems like a vacuum problem somewhere. Can you help me try to fix this myself? Thanks, Bob.
