No power and will not turn on. The blower does not turn on, but the illumination lights work when the headlight switch is on. I removed the unit to check for loose wiring or connectors. Didn’t find anything out of the norm. The vehicle listed above is a Limited modelwith dual climate control.

It sounds like the HVAC control went out, but we should check the fuses and the system grounds first. Here is a guide to help us with the climate control wiring diagrams in the images below to show you how the system works and which fuses to check.

Check out the images (below). Please let us know what happens. Also, I have included how to change out the climate control.
