My rear window on my 2001 BMW 530 is broken. At first the motor was struggling, eventually the window stop going up and was stuck at halfway. I tried to fix it by pulling the window up, but that just lead to it completely falling, leaving it open completely. I've removed the back door panel, and tried to life the window, it is stuck and when I press the window open it just clicks.....any suggestions?

the plastic panel pops off , if you had a trim removal tool it would be nice but it can be improvised , they are just tension clips , get some kind of lever behind the panel and give it a pop , once the plastic panel is off its pretty much self explanatory from there , a connector and couple small bolts , now the outside has nut under the w/w blade , a piece of the arm cover pops up to access the nut , remove w/w arm , then a grommet and under the grommet is a bigger nut that helps hold the motor onto the door/hatch , when reinstalling before you put the w/w arm back on run the wiper and make sure it shuts off and in the park position . should be a piece of cake .

The inner door panel is held in by clips and screw.
Look at the door near the door handle there should be screws holding it in and along the outer edge of the door. Once loose, and the door handle removed or the arm rest removed. The door panel then prys out , because of the clips that hold it on. Then pops out by applying pressure to the panel upward to the top of the door. The clips always break because of the design and plastic.

Good luck

I would try to test the ground the motor first, also you can duplicate the ground with no consequence. If the motor is real dirty/ dusty, you may be able to clean it and ck the brushes in it while you are there.

SOURCE: window dropped into rear door panel. How do I remove the panel & repair

the window regulator has failed. the door panel has to be removed first which requires removing the trim piece that is on the grab handle (extremely hard to remove without breaking) there are three of four screws that hold the door panel on. once the door panel is off, the vapor barrier has to be removed. don't tear it, it is there for a reason to keep water out of the vehicle. make sure you reseal it properly with window weld. once the vapor barrier is removed you will need to unclip the window glass from the regulator. i typically will take and break the tab that holds the window. once the window is loose, move the glass all the way to the top of the door. now remove the regulator, swap the motor over, and reassembly. i would recommend taking the vehicle to a bmw dealership, around $650 for the complete repair and the dealership will stand behind their repairs

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
