Are you talking about the control head for the heater, A/C in the dash? My software has instructions, but no pics.
Remove upper shift console panel
Remove ashtray
Remove register from above radio (vent)should pop out
Remove 4 screws and remove radio and control assembly
Remove 4 more screws and pry apart side claws and remove control assembly

Most panels should just pop in and out with clips.

My wiring diagram of that car is almost impossible to read. Try checking every fuse with a test light. Also try swapping the heater relay with another one to see if that will work
