We are have summertime weather out in So Cal so I turn my A/C on and nothing but hot air is coming out. Mind you I was on the freeway and just started going up a hill and I noticed a little shaking. I then turned off the A/C and everything went smooth. I got off the off ramp and I can hear a rattling and everyone is staring at me! I get home and noticed the clutch to the A/C compressor is totally burned and coming apartcwm3 So I know now I need to replace the compressor. But what else should I do?
