The AC in my truck hasn't worked well for several years. And, about 3 months ago, the compressor leaked fluid out the back and then stopped leaking so I didn't really care. But, I think that just completely de-pressurized the system because now I virtually have no AC. So here are my questions: 1) Who has done the R-134A refrigerant re-charge? How much did it cost? Where did you get it? And most importantly, how do you do it? Do I need to replace all the lines, condenser, evaporator, etc? I realize I'll probably need to get a new compressor cuz it doesn't seem like mine will work anymore after it sprang that leak. 2) Since I'm pretty sure I'll need to get a remanufactured compressor ($170 from LMC), should I just do that and then have a shop charge it with R-12? How much will that run? Do I need to replace all the lines and stuff if I do that too? Basically I'm looking to do whatever is cheaper/easier. Please give me your input and help. I'm pretty clueless when it comes to AC systems. Thanks. UPDATE: I decided to go with the R134A retro kit. Here's what I needed to do: I bought a remanufactured compressor from the local parts store because I knew mine had a leak and was not going to hold vacuum or an A/C charge. In order to have the warranty on the compressor be good, I had to replace the accumulator/dryer assembly as well. I did all of this stuff in my driveway to keep shop labor down. Then I had my next door neighbor who's a mechanic take my truck to the shop he works at where he purged out the old stuff, added the R134A fittings, drew vacuum to make sure the A/C charge would hold, and then filled it with 3 lbs of R134A. Total damage was around $360 with everything I stated above and also a bottle of oil to put 2 ounces in the compressor and 1 in the dryer. Just a note for those who live in Wisconsin - it is the only state in the United States where you cannot buy cans of R134A at a parts store unless you are a licensed dealer or mechanic. But, even if I could have purchased the R134A over the counter, I would have had a shop draw vacuum on it anyway to check the system for leaks. I'm happy to say I've got A/C again. It blew nice cold air on my trip to northern wisconsin this last weekend 3 1/2 hours each way.
