2005 GMC Envoy SLT Climate Control Panel not working

OTR2019

The information panel started to disappear completely on an intermittent basis, now it won't illuminate at all. There is no way to control the A/C or Heat. I had heard others talk about checking a fuse, but that was to re-calibrate the system, and was only with a panel that was lighted. Mine is no longer showing any info. Any suggestions ?

Looks like this?



Given the prices on those units, if there's some kind of internal power issue with the screen or the screen itself has issues, it seems replace might be more economical than repair.

Only other thing I can think of would be some kind of overall power/electrical connection to the unit. Your description of the panel disappearing on and intermittent basis and now not illuminating at all might be an electrical connector working its way loose somewhere. Just speculation, but I'd check for power getting to the unit first

Thanks for the input. I think you're conclusion is on target. I'm waiting on my local mechanic to return from an extended vacation, who's never steered me wrong. Just thought someone might have a simple solution in the meantime. Again, thanks.
