Thanks for the link, but admittedly it's over my head and it even looks like too big of a project/too much money for me D:
So guys, I'm back to this question. I have a receiver/dryer as well as o-rings, and I'm trying to buy a compressor this week. The car used R-12 previously. I just want to have it fixed up for as cheaply as possible. The only problem I know the a/c system has is the compressor, it was seized up. So how should I go about fixing it and how much will it cost?
