BEST place to find a drivers door control module for a 2000 S500??
 

My drivers door controls are all inopt. I checked for 12V going to the door control module and it's there. So the next step would to be replacing the door control module correct? Only one problem! The thing is $500 at the dealership.. Does somebody know where I can get one for cheap??

I tried fastlane and car-part already!

Is there another Mercedes cataloge somewhere out there??
