My window does not roll down how do i disasemble the door

You have to remove the door panel to get to the window crank assembly. The window has fallen off the pin the roller is on or a carrier bolt has come loose and let the window drop. You can hurt anything by removing the window crank and door handle then the panel to access the window crank assembly to see what went wrong.

Have you tried the drivers door "passenger door window switch" and the passenger "door window switch" to try and roll the passenger window up?When you do try to roll it up make sure the vehicle is running as you want the most voltage to the window motor.If both door switches would not roll the window up,try the following.
With the engine running hit the up window switch on the passenger door just as you give the door a HARD FIRM RAP.The window should roll up.It may take a few tries.DO NOT roll the window back down until you have changed or dissembled the window motor for a good cleaning.Also,check for broken wires at the door hinge area on both the drivers and passenger sides,pull each wire firmly looking for a broken wire.

Keep slamming the door, you will
surely have more problems

Remove the door panel,see the problem & resolve it

I would guess you have a broken window regulator to replace

bad passenger door window switch; replace it

Probably a bad window switch on your driver's door panel. Replace it and you should be fine.

Problem should be in the rear door switch. The motor is powered from both switches.

It could be ether a wire problem window motor problem or its jamming up when its all the way down i have a similer problem with my passenger window on my two door blazer it works fine if i keep it up sOme but if i put it down all the way i have to take the door panle off and pry it up.

I have owned several Mercedes and I would suggest looking for hidden covers over panel screws. After removing all fasteners, and pulling it out lift the panel to free it

replace the switch. They have parts made of plastic pressing on the contacts softing these babies up making them useless in a few years

Most cars will do this for tem minutes, that is, let you roll down the windows even after the key is off. When you open the drivers door, it automatically cuts all power, thus stopping the procedure. Hope this helps.
