HVAC control head, [heater controls] illumination is a different circuit then the controls themselves, blower motor will have it's own fuse, the control only supplies the ground to the blower motor,
same with other function, the control head supplies grounds to the "Mode Control Motor" it has it's own fuse.

I would be checking fuses and dash harness plugs, remove HVAC control head and make sure it is pluged in properly, you may be able to access the HVAC plug(s) by removing the HU.

Make sure all plugs are properly plugged into the fuse box. 94
