Chevrolet Malibu Climate Control/AC Issues

  • I also had 2 Malibu cars, 1998 and 2001. Both my vehicles had the same A/C problem, with that module button switching from the a/c position to off. Here is what I have found about it. The module can be replaced, but it is likely to only be dirty and needs only to be cleaned, (much like cleaning a smoke detector). Go to the link below and there are instructions on how to do the necessary cleaning. Good Luck, it works. http://www.imcool.com/articles/aircondition/AC_ControllersAreRepairable.pdf

    This works perfectly well... 2004 Malibu, 1 hour, pry tools to remove the front bezel, 2 torqs screws, and the climate control unit pops out. Took it inside, tore it down to the control board, Went over all the contacts with a pencil eraser, then washed it all down with Electrical contact cleaner. I took the 2 dials apart, cleaned all contacts, and replace the grease.

    My GF was going to have the dealer do it for $150 in parts + Labor.
  • Did you ever get the AC straightened out? I am experiencing the same problems as madog0324

    I cleaned the contacts for the temperature rotary switch and put a little more bend on the two contact arms. I haven't had the intermittent a/c compressor since. I am still having the THEFT SYSTEM issues.

    My A/C stoped working along with the engine temp. gauge. The next time I started my car - it worked. Now 2-3 weeks later it has completely stopped working - it just blows hot (outside temp) air. Computer issue? thermostate? Looking to see if we can fix this instead of $$$$ at the dealer. Thank you!
  • The A/C compressor & both cooling fans quit working today. R-134 charge is good. Temp guage works. The car almost overheated in rush hour traffic. It cooled down once traffic started moving. All fuses and relays check out good. The a/c light on the HVAC control lights up, but the compressor does not engage. Has anyone else had this problem?

    HELP..... So my wife's 2002 Malibu LS has been having similar problems with the AC as well. For awhile now the car has been blowing nothing but hot air. I turn the AC on in car, rather it be on the re-circulate or just regular it still blows hot air. But, the heater works just fine. The A/C compressor is running so I know its not that, so I decided to change the AC compressor relay.. still blows hot air. Car has Freon in it as well (been awhile since it was changed out) but I would still think some cold would come threw the vents, but nope..all hot air. Please help with any suggestions or ideas.
