I have a 2001 Malibu. On the control panel for the air conditioner, the ac button(the one with the little green light) blinks on and off as if it has a short in it. When it goes off, it stays off, but if I change the fan speed from one speed to another, it comes back on for a little while. This is very frustrating. Could this just be a short in the ac button, or could it be something else?

I have similar problem. Mine switches from recycle to outside air. Sometimes the AC shuts off too. VERY frustrating, happens continuously. I removed the whole module from the dash, checked hoses and electrical, but no change.

I have the same problem as klwdesigns with a '98 Malibu. Had the control panel changed 2 years ago and work ok up to about 3 months ago. It's 120 in the Southern California desert and I need the ac. Send help to morrismontgomery@msn.com. Thanks

After reading the instructions, I tried to "clean" the controls by turning the nobs back and forth 10 to 12 times and pushing the switches several times with the key off. It has helped some, but there still are problems, so will try to take it apart. Thanks.

my 2001 Malibu has this problem, blinking A/C light. I will try the 'DIY' fix. http://townhall-talk.edmunds.com/direct/view/...

I have had the same problem with the car I drive at work. My boss took the car in for another problem and told the Chevy dealer about the ac not working properly. The car gets cool when I hit the "inside air" or recycle air button, but after a while it switches itself back to outside air. You can definitely tell a major difference in the car when this happens. The mechanic told us the ac was working correctly as it was designed. The ac will turn itself back to outside air after it has been running on inside air for 15 minutes or more, but after a while it should turn itself back to inside air and get cool. This system is really been difficult to deal with in the hot Texas summer temperatures!

I have a 2000 Malibu with your exact problem. I'm roasting in Florida. Any suggestions?

I have a 2000 Malibu with the A/C continually switching from recirculating to fresh air (because it's so hot I want it to stay on recirculate). I'm roasting in Florida. Any suggestions?

My malibu did the same thing last year and they replaced a switch in it. It started doing it again this summer. The Chevy service Dept said now they found out its suppose to do that Ha!...HA! go figure. I just keep changing mine back to recirculate if it switches.

I have a 2001 Chevy Malibu that keeps switching between recirculate and outside air and it also periodically shuts off completely. I was doing this a couple of years ago while it was still under warranty and the dealer switched out the whole center module to fix the problem. 2 yrs later it's doing it again. If anybody determines why please post the answer.

Hello, Same problem and it's the button. I've complained to the National headquarters that they should call a recall. I have a 2003 and they new well before I bought mine that the button needed to be fixed. I've had such a tassle with GMC that I'm refusing to buy another GMC product. GMC doesn't care that we are suffering and don't want to fix the button because my car is out of warranty even though this is the 3rd time it's broke! And for the person above...it is NOT suppose to switch itself; whoever told you that told you that to get you off their back.

I have same problem with my 98 Malibu, that the AC turns off whether I'm on outside or recycle air setting, but it is worse in recycle mode. This is a weird problem, because there is no consistent or repeatable conditions that cause it. Somedays it drops out once, others many times. I don't think it is mechanical, since road bumps don't seem to influence it. However, I've found that pushing on the control panel faceplate right above the fan speed switch always turns it back on ! Try that and let me know if that works, because it could point to a common cause. I think it is an electrical grounding issue, and will tear it apart one of these days and share my findings. For now, I'll try the fix recommended above.
P.S. I have reduced the dropout rate by first turning the fan speed to 3 in Recycle Mode, and then turning on the AC. That seems to work better than starting with the AC button on.

Doing as I did in my post of July 26, above, the controls appeared to work better for 10 days and then the light started to blink again. It appeared to me that the problem was in the fan switch, because, as is reported here, changing the speed causes the air to stay on. One day with the power off I turned the fan switch back and forth for 15 to 20 times and the system has been working fine since. Perhaps the contacts on the fan switch are dirty and this cleans some of the dirt off so better contact is made or whatever.

I have the same a/c problem with my 98 Malibu. The AC light begins to flicker and hot air blows out. I found by turning the fan speed down that usually solves the problem. My best solution was driving my Toyota when it gets hot.
