So since i have purchased my 98 GT i have been going through the car and fixing all minor Issues. My biggest issue is when i bought the car the guy told me the a/c did not work. I decided one day to just turn it on while i was driving, amazingly enough it blew cold as ice, only issue is when i stop at a light or am just idling it blows hot. I have a little experience with a/c but to me this is weird. When idling the compressor does come on and cycle,blows air but is hot. As soon as i accelerate it blows cold. Any ideas?
