New to me 2002 Yukon 5.3L with rear air. Horrible noise upon acceleration with AC on. Tensioner is jumping up and down, and according to GM TSB #03-01-38-019A, it is caused by the compressor slugging. The compressor is very low on the engine and apparently liquid refrigerant and oil can pool in the compressor causing it to slug (hydraulic binding). I already replaced the belt and tensioner.
Is there any way to get it out of this condition without replacing the compressor like TSB says? What if I idle it for a long time, as it doesn't seem to do it at idle. Would that eventually pump the accumulated fluids out? Heat up the compressor?
