I'm working on a 2003 Chevrolet Malibu. The A/C light flickers on and off and it switches back and forth between cold A/C and outside air. I've tried replacing the A/C control unit and it didn't fix it. Replaced the BCM and that failed to fix it also? Checked R134 levels. All checked ok? What could be the cause? Any sensors? Compressor? Let me know! Thanks!

For a complete do it yourself fix (it's not hard), you have to go to Beatnik Termite's post on page 3 under the heading.
