Heat/Air system has no power at all

Asked by dwest88 May 07, 2024 at 04:52 AM about the 2005 GMC Yukon XL Denali 4WD

Question type: Maintenance & Repair

I have a 2005 GMC Yukon Denali XL. The entire
heating/AC system for the front does not have any
power to it. There is no display, no lights,
doesn’t even turn on. The rear system works fine
although it’s a separate system with separate
controls. Could this be a fuse? Electrical? It’s my
daily driver with almost 184,000 miles on it.

Blown fuse or an electrical short. If it's not a fuse, have a mechanic with a multi-meter track this down.
