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.
