When I bought my e34 2 years ago, the AC compressor was completely locked and the belt had been removed from the pulley. I was thinking about getting a new paint job but with the heat in South Louisiana already setting records in mid April (91 Degress today), I'm thinking that the money would be better used on repairing the AC system. My question is how much would I be looking at to get the system back up and running? What parts would I have to buy new and what parts could I get used? Just looking for some opinions. TIA.
