Hello all...I am new to your forum. I need help here with a AC diagnosis. The car started making what appears to be whistling noise coming from one of my pulley accessories it changes pitch upon accelerated. I took a stethoscope a determined it was coming from the AC compressor. I also noticed a lot of gook looking build up around the pulley accessories and in some places like a very black powdering film build up. I looked at the bottom of the compressor and there appears to be oil coming from it. The air is still blowing cool so I really have no clue what I need to do first. The noise happens whether the AC is on or whether it is off but it is for coming from the AC pulley. I can here the clutch kick in when I turn it on and off. Any suggestion would be greatly appreciated.
I also forgot to mention that the lines connecting to the compressor appeared to to have oil spray on them. Could this be from oil getting on the belt slinging the oil or is it from some kind of pressure release from the compressor? Really need help here fellas! I am considering bypassing the compressor unitl spring but if it is something I can fix without buying a new compressor I will do it.
Take the belt off and spin the pulleys by hand. If the A/C one is noisy you can replace the bearing without replacing the whole compressor, often with the compressor still in the car and not needing to remove the refrigerant.
Hopefully that oil came from somewhere else. Clean it off and watch closely to see where it reappears from.
