I have an '03 Silverado K3500. This past summer, the blower motor quit working on (5) high. The other 4 speeds all work fine, just the high speed is inop. It wasn't an issue in the summer, but now it is cold and I need a little more heat in the cab.
Is the resistor the most likely cause of this or am I in need of a new switch?
If it is the resistor, where is it and is it a pain to get to?
Is GM only the best option or is the aftermarket a viable parts solution?
Any and all help will be appreciated. My frozen feet thank you!!
