Hi All, I know this is a common topic but I haven't found any posts relevant to my situation. I have an 03 1500 silverado with the higher trim level that includes a digital dual climate control. It has a blower motor control module rather than the seemingly more common resistor. I had the same problem last year and replacing that module fixed the problem. Well six months later the blower plain quit again. I figured I burned through another module but replacing it didn't fix it. Neither did replacing the blower motor. Thats where I'm at now. I didn't find any fuses that appeared blown. Aside from taking it in what is my next logical step? Any help you guys could offer would sure be appreciated. TIA
