Replacing the windows in a W114

Hello chaps,

I am trying to replace the front and rear window in a 72 W114 after a break-in.
I have the glass panes, but I do not know how to remove the door panel and fit the new panes.

Does anyone know of a guide I could follow?

Many thanks,

I do not have a guide, but you can do the job pretty easy.

1. Unscrew the door lock knob
2. Pull up the sill cover by the window
3. Unscrew the bolts holding the arm rest on
4. Remove the black plastic cover in the door handle with a small flat head levering it from the back to access the screw holding the trim on. Remove the trim
5. Pop off the window winder handle cover from the back and then pull toward the knob to free the circlip part. Pull off handle
6. If you have the wing window, pop the cover off with a thin flat head, and unscrew the philips screw holding the knob on. remove knob
7. Unscrew the door lock trim at the rear of the door
8. All trim should now be off.
9. Using a putty knife, start at the bottom of the door and slip the edge between the metal and panel and twist until a clip lets go, continue along the bottom, then move to the sides, removing/popping out the clips carefully.
10. With panel out, the weather proofing plastic should be exposed. Remove the plastic and inspect the window mechanism. You can lube and replace broken parts at this point.
11. With the window wound all up, hold the glass in the up position, then crank the system down.
12. Remove the lower arm and slowly lower the glass, pulling it toward you as you go so the glass clears the mechanism.
13. Clean out all the muck and mire in the door, lube the tracks and make repairs as needed.
14. Put a blanket on the lip of the opening and carefully lead the new glass into the track by hand. You might need a third or fourth hand to help. Have them hold the bottom while you place the glass.
15. Lift the glass all the way up to make sure it slides on the rails well and then lower it onto the arm and secure it there.
16. Put a heavy plastic or roofing felt over the opening to once more weatherproof the door.
17. put it all back where you got it from in much the reverse of how you removed it.
18. Feel free to use as many salty words as required for the task. Do not use any beer or intoxicating beverages until after you have exhausted your trove of salty words and the job is safely over.

item num 6 , the round knob has a hole at back side , you insert a curbed rod to push the cover out , using a screw driver will leave marks .i would invest in a body manual for this car , it s all in there [ ebay or ?]

I was bound to miss something. Late night post and I had to scavenge my brian for what I did to get the window felt in my 220D in 2005.
