A/C Help?

[e30loverSC]

Well Im making a list of things to fix on the E30, AND a/c is one. When I bought the car the guy said it had been converted to r-134... well it worked for a year or so and quit.. I recharged it and it leaked down. Well I just quit using it for a while then all the sudden the compressor was making a terrible noise so I cut the belt. I want to get it working again.. How do i know if it has truly been converted the right way. What should I do to fix it right? thanks - Hunter

Noise from the compressor when you weren't using the AC could be a bad compressor clutch. The clutch can be replaced, but if the compressor is original & worn it probably makes more sense to the complete unit. The next task would be to find and fix the leak. That may be a simple and easy as replacing all the o-rings that seal the lines. Or the leak could be bad line, in the evaporator, or condenser. Then replace the drier, evacuate the system, and charge it.
