Hi, I have the same problem with my 2004 Malibu. I had it replaced in 2006 under warr. After about 2 yrs, the AC light started blinking and it would go from recirrculating to fresh air. Last year on 7/24/08, I had it changed again and I paid for it! $480 bucks! Now, only a year later, it is doing it again and of course it is out of the Warr periode. If this is a big problem, why doesn;t Chevy do something about it!

david, it was the whole unit; and it only cost me $30 bucks. It came as a whole unit, just unplugged the old one and replaced.

I have a 2000 Malibu and the air coming out of the AC does not blow where you have it set. It mostly blows from the floor vents. I have looked for a vacuum leak but cant find one. Should I try cleaning the switch?

The switch o-rings might be worn, I think your on the right track.

Cleaned the switch but the air still does not blow where it should.

Did not see any o-rings in the switch.

I have read all of the posts here and have not found a solution to my problem, yet. I have a 2004 Malibu Classic with manual air. The a/c worked intermittently last fall and then quit. The rear defroster has also stopped working as well as the re-circulating air control. I followed the directions given for taking the control apart and cleaning, but that did not fix the problem. I verified that the botton switches are, in fact, functioning, as in normally open and closed when pushed.
I removed the a/c relay and by connecting the relay contacts together with paper clips, the a/c compressor will turn on and work (can't very well control the a/c with paper clips all summer!) From the electrical diagrams that I have looked at, it appears that the Body Control Module (BCM) is not sending a signal to the a/c relay.
Has anyone had any experience with this? BTW, all fuses are good.
Any and all advice is welcome. Thanks

Has anyone checked for proper amount of 134a in your ac system.
Also are the pressure sensors working properly.

Thanks gonogo, for the suggestion. I will verify these items tomorrow morning; however, I do not believe that the amount of 134a should affect the rear defroster or the air re-circulation setting, would it? If it does, GM is more screwed up than I thought! After verifying the charge amount and the sensors functionality, I will post again with the results.
