Anyone have to replace a blower mower resistor on their truck? If so, any pointers? I got in my truck today and the blower wouldn't come on. All my lights work for the controls, and you can hear the compressor engage when you turn on the A/C, but there's no fan turning. I see this is a pretty common problem, and watched a few YouTube videos, but none deal with my model year. Figured I'd check here, as I'm not a member of any Chevy forum. TIA.
