Climate Control does not Work

[hooahaggie]

Today discovered battery was dead, boosted to get started, but then noticed the climate control system panel would not turn on/operate. I checked all fuses and all were good. I am stumped. Is it possible for the panel to have burned out somehow when I boosted the the battery? Any help to further troubleshoot, or for any known solutions is appreciated. We live in Germany, so getting parts is going to be a pain nonetheless so hopefully it's a simple fix. THANKS!

Guess I forgot to mention...it's a 2003, YUKON XL 1500 SLT, digital controler. Also, it's been a few months but the driver and passenger seats will also not adjust, and the seat heaters will not operate...is there an overall electrical gremlin somewhere?

Well after doing some reading on this forum, I went and disconnected the negative terminal on the battery. It actually worked and the climate control panel now works! Awesome quick, easy fix that I can't explain the technical why's/how's, maybe someone out there might be able to expand on...
