Anyone know anything about a/c's? Here is my problem. I had my a/c serviced because it wasn't blowing cold enough. "The shop" told me that my a/c was "overcharged\too full" and that they had to empty it then recharge it at the appropriate level... A week ago my a/c starts to squeal...LOUD! A fellow mechanic takes a look at it and says my a/c compressor w/ clutch is out. And get this. there wasn't any oil in the clutch\bearings. So what I believed happened is that after emptying everything & "charging" the a/c, oil was over looked. So I have been running the a/c for 3 weeks and finally the sucker just got too hot fused & welded together. Does anyone understand me? Any suggestions? Can anyone help? Hey even if you don't have an answer thanks...

Well take it to a mechanic and have them fix it.
