For the first half of the summer I have been driving around without a/c because one of my lines was cracked and I couldnt find a replacement. Low and behold I finally found on on ebay. Fixed it charged the system, air blows freezing cold, problem solved right? No, now that my a/c is fixed when its on a terrible screeching sound comes from the compressor. Sounds like a belt. I tightened the belt it still makes the sound, I sprayed some wd40 on it and it stops until it dries. The sound does not occur when the air condition is off. What could this be, whats the fix?
