2006 GMC Yukon Slt front air vents not blowing on any setting. Please Help

ok well that leaves 2 possibilities then either the resistor kit is no good or the control unit is bad, unless your incredibly unlucky and there is a wiring short somewhere in between.

That’s what I was thinking too. Tomorrow I’m going to swap out the resistor with another one to see if that works. If not I’m going to have to find a new module so I can test that as well. Thanks for all your input!

Nobody mentioned the other half of any 12v system. Could be the motor lost it's ground wherever that may be. You could try a jumper to the negative wire of the motor. We always check for power but not ground.

I was able to figure it out! It was the resistor. The new one I installed was defective so I swapped it out for a different one and it worked immediately. So glad to have air/heat again thanks everyone for your responses!

Awesome, glad to hear you have heat again. Must have been an aftermarket resistor?
