Help - Push Button Climate Control
 

Can anyone post the schematic or the way the board works. AL that technical electronic stuff. I work at a Clothing Manufacurer and we send out motherboards and chips to some of the more sophisticated machines here to get repaired, going to send him teh push buttom control board to see what up and if it needs to be repaired, see if he can do it.

Climate Control Pushbutton
 

Try George Murphy in Oak Ridge, Tennessee. I bought a rebuilt one from him, and it works great. He knows Mercedes' climate control systems, too.
Hope this helps.
