Rear window fell down need help fixing - 2000 Buick LeSabre

The window in fixed to a window regulator. When it breaks it lets the window go into the down position. You will need to replace the plastic regulator. Not too hard. There are videos on line to help.

If your careful you can get the door panel out of the window trim at top with out breaking it. Hooter day is best to do it as the plastic panel is more pliable. Once out wedge it back some and pull the trim out. This will give you a good inch plus gap to work threw. Most like the cable has wrapped around it. Flash light to see it and bent coat hanger, long screw driver or bar. You should be able to get it open.

Hi, please replace window glass motor system.

You don't need a manual,won't help you
Remove the door panel and replace the window regulator

you cant fix cable, you need the Window Regulator

you will have to remove the inside door panel to access the window.

Your regulator needs to be replaced.

open the door panel and locate the lock. screws are usually found on the handle inside, clips under the panel.

All its done its just come off its tracks so remove the door insert carefully place the window back on the track and tighten it up using basic tools and no the door insert/panel can come off even if the window is all the way up. Hope this helps.

If your window is off the track and sliding forward (leaving a gap at the rear) when you roll it down; the plastic guide that fits into the track is likely broken and very easy to replace. There should be a hole drilled into your at the top rear of the window where a plastic clip can snap in. Most auto part stores have these for sale or the dealer can be a last ditch alternative. Installation is a snap, literally (forgive the pun), roll your window half way down, you fold the clip over into the hole, snap it together and fit the window and the clip back in the the rail. Usually you can just grab hold of the top of the window and push the whole thing into the rail. Good Luck! Nick
