After further inspection with a friend that knows cars, we concluded that the a.c. compressor was locked up. The belt was grinding on it. It wasn't moving. So I cut the belt. She's quiet like she used to be. That sucks because now I'm going to have to replace the compressor and have to deal with non power steering for a week. When I get paid I will definitely tackle this issue. In the end I hope to have a.c. and my power steering back. But at least she's back to her quiet self. How hard is it to replace the ignition coils and the idle air control valve?
