Having problems with your 2003 Chevrolet Silverado 1500 ?
When A/C is on and MAX button is pushed, I get a flapping/popping that seems to be coming from the area below the glove box. For some time now, even with the A/C off, when I first start the truck or when shutting down, this "popping" will start up and last for 10-20 seconds.
The recirc. door motor has gone off the end of it's useable range it needs a new actuator and a program update of the a/c module to prevent from it doing it again
Windings in A.C. motor may be going bad
