I had to take the door trim off. Be very careful with the interior door handle as I broke the plastic clip that keeps the bar that moves the door lever in place on the door handle. I cannot get new ones except from Brindley, off the Penn Road in Wolverhampton.
Lower the window down and you can see that two bolts hold it in place. I took them out and had a game to refit the one. Just loosen them and slide the window to the right and the window will come out. Then tighten every bolt. Then get the window glass into the rubber edging and push it down onto the rail and retighten the two bolts.
Mine works but the actual mechanism is worn. At least I can put window down aout a third of the way and back up again.
Hope this helps.
