First order of buisness on my new to me k10 suburban is getting the ac fixed before I can put my daughter in it, texas summers are rough. Anyways, the volt gauge and blower motor are on the same fuse correct? That’s what I found through my research, anyways, checked the fuse, it’s good, checked both sides, 12 volts. But neither are working? Should I be looking for a broken wire now? Is it ran in series? I’m stumped on where to start on getting this fixed

The lower speeds of the blower go through the blower resistor, and the highest speed uses a blower relay and a fused direct wire that runs across the top of the firewall over to the power junction. You could have a blown fuse (25 or 30 amp?) in the high speed wire, or a bad relay assembly. The resistors and the relay are mounted on the A/C plenum under the hood.

Found the problem, the disc on the inside of the climate controls had come apart, so no power was getting passed it. 12 volts in on the connector, and the blower works when jumped, so just need a new climate control panel!

LMC sells them if no one here has a gently used spare OE unit for sale.

In case you did not know.
