Question about 2007 Chevrolet Silverado 2500HD
Thank You first of all
My 2007 chev 2500 diesel has a defrost selector switch that will not change to the defrost setting thus very frosty window.
I would begin to suspect a faulty switch.
If this vehicle is equipped with vacuum hoses for the controls, then I would first check hoses for cracks and leaks.
If that is all good then I would check resistance in switch with a voltmeter according to repair manuals specs.
