A/C Compressor

fillup · 05-27-2010, 12:59 PM

I have an 02 WRX and have been having trouble with the A/C. When I turn on the A/C sometimes it's fine but a lot of the time it makes a grinding noise and my car loses major power for a few seconds. Do you think I need a new A/C compressor or could it be something else (and hopefully cheaper)?

Check the A/C idler pulley. My A/C was giving me fits since having my timing and accessory belts replaced last summer. When I turned on the A/C this spring, it wasn't working right. It took two trips to the dealership to properly diagnose the problem. around that time, I came across a couple threads on NASIOC discussing how the A/C idler pulley does go bad. Good luck!
