Removing the fuse for a few minutes and turning the controls on both driver side and passenger side to the highest setting and then turning them down slowly until the system started cooling has worked for me. Thanks for the suggestions---saved me $2500.00 on a useless dealer estimate to fix problem. These dealers are dangerous---they were the ones that caused my problem when they unhooked the battery while replacing my ignition switch.
This is a good forum.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

It sounds like the battery has a dead cell in it. Replace the battery. If you have an alarm installed remove the in line fuse from the alarm and see if that stops the battery drain.
