Rear window will not roll up on mercedes e430 possible causes

Remove Inner door panel, usually, the door handle has a screw, behind the lever, on the inside, and may be covered by a plastic cover, take the screw out, and move the handle forward, then take, the side on clip, off, the rod.
remove, any inside door handles, screw to door, and then starting from the bottom, pull the panel towards you, unsnapping, the plastic clipps, holding them on the door.
Roll window down, till you can see the 2 nuts, holding the bottom of the window.
Now, run the window mechanism, all the way down, away from window, while holding window.
Now it is loose, twist the window, inside the door, front down, back up, so, it comes out, the top
Put back, same way

You'll need to remove the door panel from the inside of the door. Go to an auto parts store and ask them for a trim removal tool and a pry tool to help remove the window crank handle - tell the clerk what you want to do. Use the trim tool to unhook the catches around the outside of the door panel. Remember to unscrew the arm rest before you try to pull the panel off the door. Once you have that off, you will likely find that that the glass has slipped off of the track that the bottom of the glass rides on. It helps to have someone help you hold the glass as you lift it up and reset it on the track. Make sure that it is seated squarely on the window track and that it rides up and down smoothly before you put all the parts back together.

Good luck!

Remove the inner door panel & replace the
regulator cable assy,switch motor over the new one
if possible

Sounds like window came off track

well, when this happens to me, I grab the glass with a pair of pliers with tape on the window top, to prevent damage, Push on the switch to go up. Sometimes motors stick in the upward direction when down too low.

Tabs at top,lower window prise off

If your unable to open the rear door you should just be able to remove the inner door liner from inside the truck, climb over the back seats. Once the inner door panel is removed (remove all hardware, handles and such) the panel should pull off. To do so grab the pavel at the outter edge and pull away. As you pull away feel for where the fasteners are and concentrate your force of pulling there, pop out each one, one at a time. After removing remove plastic film and look into the inner door, it is there you should find your problem.

I hope this may have assisted you,

This panel is held in by plastic snaps. After all the screws are ou it pops off not a sliding type. Hopefully your window rolls down it is easier. !st take the plastic cover off of latch mechanism in rear of penal On the seat switch you'll find the top wooden portion pulls off grab from the bottom. then there is a bracket that unscrews and the seat switch wood pops out. next open the armrest and you'll see a plastic cover held in by a small black screw. remove and then remove the big screw behind it, I believe there is also a screw in the front of the map pocket and possibly 2 more in the center. pop out the light at the bottom of the panel and un clip wire harness. Next pop pout the top side view mirror cover. I believe there may be a couple of plastic grommets on grab handle that pop out giving you access to the screws. Next pop off the door panel by grabbing at the bottom and pulling outwards. be carefully because there is a vacuum line attached to the map pocket lid locking mechanism. once panel is loose un clip vac line and electrical and grab handle linkage. you should then be able to remove panel completely. i do not have an sl in front of me so look very carefully for any screws I forgot to mention. This is the best I can do from memory. good luck

The door panel is held onto the door with clips but first you need to remove the screws from the grab handle on the door panel. then pop the bezel off around the inside door handle. very carefully!!! then using a clip tool pry off the peice that covers the rear view mirror nuts and pry gently all the way around the door panel until its loose then lift it up slightly to unseat the window channel strip off the door, then unhook your wires. As for the window roll it up, tape it to the door then line up the 2 10mm bolts that clamp it to the regulator with the provided holes in the door, loosen 'em up roll the regulator down and remove the window. Have fun guys!!!
