If I start the car with the climate control in any given position and leave it, it works fine. If I start it in an a/c position and move it (max a/c to a/c or to defrost) or move the temp setting away from 60, the thing is cold for a varying time then switches to maxium heat. Once in this heat mode, it will not switch back to cool no matter what the controls are moved to. If set the controls to 60, shut off the car, set the control to max a/c, and only max a/c, then restart the car, it will usually return to cooling. Then I can shut off the car set the control to a/c, restart, and it will stay cool. The "usually" occured the other day: after the max a/c restart, the heat came on again. I shut off the climate control and a few moments later the 'check engine' light came on. The car was running fine and the gauges were ok. So, I shut off the raido to listen and the check engine light went out. On a hunch, I flicked on the a/c and it was cold. I turned on the radio and it worked, no engine light. Any guesses?
