i drive a 2001 C320, and for the 1st time when i try to adjust the right mirror or electric chair they dont move instead the left side moves and the right window does some funny stuff when i try to pull it up..im assuming its the front right door control module..now i have never taken the door panel off before n today i looked at it, there wasnt any visible screws..can anyone help me where to start if i want to take the door panel off to get to the module??? any diagrams would be a lota help too

 

There's a very good DIY posted on removing the door panel but I don't believe what you are looking for is in there. I 'believe' (don't know for sure, just a hunch) the mirror control is incorporated in the seat modules, that are located under the seats. The reason I say that is because seat and mirror memory come together as an option.

 

take a flat head screw driver and pop off the interior door handle cover there's two T-30 screws behind it. pop off the airbag logo cover and there's another T-30. remove the hindge cover with T10 or T15. remove the pillar speaker cover. pop off the clips hold the panel and lift up and out.
