Having problems with your 2003 Chevrolet Monte Carlo ?
Have a 2003 Monte Carlo SS. Usually happens when I first start the car. The cruise control light comes on in dashboard at the same time the air, heat and defrost won't work. After a few minutes everything works normal or sometimes when you restart car.
Most of the newer cars especially the new chevys are all ran off the bcm or body control module, i would have someone with a snap-on brand tester check to bcm and the parts of your car first to make sure what is all wrong, could just be a shorted wire or a broken vacuum hose
