99 Tahoe No heat controls, fan, rear defrost.....

What is the typical problem for this? I dont think its the blower motor because nothing on that heater/AC control panel works except the lights. Its stuck on floor heat. Cant adjust anything. Any help would be awesome. dont want to just start randomly replacing things like i did on my K1500.

Welcome to the neighborhood!

IT sounds to me like you need a new control unit in the dash.

ive seen where the resistor and motor for vents were bad and made it look like it was the panel.
