Heat/Air system has no power at all
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.
