95 Civic EX: Within the last week my A/C will chatter when engaged. I beleive it is from the AC compressor. I used belt dressing on all the belts, however that did not seem to do anything. Is there anything that typically would cause this? Anything I can do, short of taking it into a shop? The A/C condensor was replaced about two years ago after a run in with a deer. The system was fixed up, recharged, and was working as well as can be expected considering its a 11 year old economy car. Along with this chattering, the A/C will blow non-conditioned air. IE: A/C is on and drawing power -- I can hear it is engaged However I will be getting warm humid air from outside, or partially cooled air. Disengaging and reengaging the AC will temporarily solve this. In my head, I know that the A/C Compressor has probably warn out and needs replaced, but I'm hoping OT can prove me wrong.
