Hey Gavin,
Tom Ott here, I was in the gold 86 GT that exited off 85 at J. Carter Blvd in front of you. All the guys who saw your car up close agreed that it must have been garaged it's entire life, am I right ? My a/c is out , too, as we discussed. It MUST be something that happens to GM a/c of a certain age. My problem is simply a new compressor. A remanufactured unit is about $165, plus freon and other parts (needed to extend compressor warranty to 1 year) will cost me about $235 plus install labor. I use a mechanic out on Loganville. His name is Lee Arnette. I don't have his phone # on me, but I will post as soon as I can. What are you doing to the engine? How many miles on it? A good guy to talk with is our fearless leader, Charlie Sewell. I can get you his number, also.
well, gotta run, great to see you found our website (the links here also have good info..Pennocks Fiero Forum)
