Electrical or computer problem. temp gage and A/c don't work on 2007 Chevrolet Malibu

3 times in the last 6 weeks when turning on the A/C or defroster, I assume some computer problem occurs b/c the temp gage goes to 0(does not), the A/C does not blow cold air and on 1 occassion the engine check light came on (the time my wife turned on the defroster). and also I beleive the radiator fans automatically kick on. So far when i have disconnected the car battery and re-connected the battery the temp gage and A/C will work. No other problems with the car at this time. What is causing this? Sensor, the computer? How can it be fixed? i will go out and disconnet the battery a 3rd. I did not check for the diagnostic code when the problem happened the 2nd time. 1st time and the last time the service engine light did not come on
