1999 Blazer

My mom has a 1999 Chevy Blazer LT and her entire climate control panel is dead, the fan, AC, rear defoster the works is dead. We are takeing it in to the shop tommorrow, just wondering if this is a common thing in 99' blazers or if its just a fuke thing

Havent seen that problem yet.
Electrically the only common problem on that model is ignition switch failures.
