First of all, are the dash lights also out......if so, the rheostat behind the instrument cluster may be the cause........
The climate control amplifier is partially responsible for receiving requests from the control head (the buttons that you push), and sending commands to the servo to execute the climate control changes you requested. Example: I have a 1980 450 SEL. The climate control amplifier is behind the glovebox. I'm in the process of refurbishing mine with new guts. I knew mine was bad because the heat wouldn't come on.
if all buttons and lights went out on your climate control then either its not receiving proper power or ground, or the control panel assembly is faulty.

It is on if you selected it by pushing the button.
I almost think you are talking about a GM vehicle ,?climate control.
using radio keys under the temp buttons down u will see the slots on both sides where the keys slide in and lock then just pull on keys and climate control will slide out
The fuses in the 1989 Mercedes 300 control things like the lighting system, the door locks, the wipers, and the instrument gauges. The fuses also control the trunk latch and the turn lights and brake lights.
On the 2003 model SL, at the digital clock on the dashboard, you'll see a couple of little black buttons....those buttons control the clock. I believe you have to push both buttons at the same time to activate the settings.
there are nine buttons on a wii control
Pull the dash trip off gently from bottom to top, (just the dash trim by the climate control) and there will be 4 screws on the climate control module. Its best to buy a used 1996-1999 Mark VIII Climate Control module, since they have "Hard Buttons" on the climate controls. Pull out the old one, and replace with the new model. Newer model climate control modules are totally compatible w/the 1993-1996 models.
