be careful! don't pry too hard, you don't want to break the little plastic clips that hold the panel to the door.

Step 3: Undo the connecty bits

This is a very important piece. Don't tear it... if you do, it is easy to repair with duct tape.

Step 5: Pull off the sweeper

pull of the felt sweeper that is on the inside of the window. doing this will make removing the window easier.

Step 6: Unplug the Window regulator motor

These little clips are frigging annoying but they work well at keeping plugs plugged...

Step 7: Unbolt the window regulator from the door and the window.

you should now be able to slide the glass up through the top of the door and out of the frame.

Step 8: Glass! don't break it

set the glass out of the way in a safe place while you swap out the regulator assemblies.

Step 9: New and Old

I made sure I had the correct regulator before I continued any further. I also wanted to inspect my old assembly to see what had gone awry. 

Step 10: Plug the plug

Step 11: Install the regulator!

Step 12: Test

I loose fit all the fasteners before re-installing the door panel so as to make sure the window would not bind in the channel.
then I tightened all the bolts and started reassebly

Step 13: Plug all the plugs, clip all the clips and re-install all the screws!

if you forget to clip or plug something now you'll just have to pull the panel off again... double check!

If it's just the worm screw that is broken, and the motor is running fine, this is a brilliant, cheap and easy fix: http://www.lunghd.com/Tech_Articles/Body/XJ_Power_Window_Regulator_Fix.htm

I used about 1 hour for the whole process, but almost 3 days before I found the link to this genius walkthrough :-)

The cotton pin is approx 2,2mm, and I used a 2,5 mm drill for the holes.

Nice write up. I just did it today! One suggestion would be to tape the window up in the door frame after unbolting it from the regulator. This eliminates taking out the sweeper and pulling the window. Thanks for the assistance so I didn't miss any steps. :)
