hI THEGROVE45, did you ever get this problem fixed. I have the same problem, and took it into the dealership, they told me they would have to replace the whole unit, and told me the light inside there was not a light bulb but a wand lit up with LED.

The problem is the turn signal/headlight/hazard switch assembly on the steering column which the brake light wiring runs through. The part is easy to change and cost about $50 at most parts stores
SOURCE: climate control not working
I had the same problem on my 2004 GMC Yukon XL.
Still under warranty the shop was able to reprogram the climate control system and tell what was wrong rather quickly with a OBD computer.
That’s when they found both of the climate control (driver and passenger) side actuators were bad and the control unit that tells the actuators where they should be was also bad.
The truck was in the shop with most all the dash, seats, consol, and steering wheel out for a week. The cost was over $1200.00.
That has seamed to fix the problem. Good Luck.

You might wanna check and make sure the heater switch didn't go bad. It could even be the blower motor itself.

It could be a bad blower motor - tap on the blower motor with the end of a hammer when you have the switch in the on position - if it comes on then it is a bad blower motor. If it doesn't come on I would check to make sure you are getting power and ground to the HVAC control head.

would the blower moter resistor effect the interior lighting as well?
