Thanks. I think that is the only way to go now.

Help! Bought the new regulator. Swapping the motor was a snap, and I was really proud/happy when I reinstalled the entire system without any problems. And then . .. . . . tested it before even putting the glass back on, and it seemed to work beautifully. So I reassembled just about everything: placed glass in the appropriate "jaws" which were at the very bottom of the door, tightened them in, and hit the window button. Window went up nicely until about half way up, when it suddenly slowed considerably; it seemed to labor going up any further. Long story short, it is now up, with about two inches left to go for a full close, but it will not move either up or down. I can hear the motor wanting to work, but nothing happens. Is there a trick to this? Some adjustment that no one has disclosed yet? Some magical spot at which the window glass needs to be installed for the entire system to work? Assuming I can now get the glass out again (may be very hard since it is difficult to reach the Jaw, how does this system get "tuned??"
Thanks.

Nobody answered when I asked the same question recently:
- Do we have a step-by-step DIY for ADJUSTING window glass when replacing the regulator?

For the record, the exact question I asked (still unanswered) was opened today:
> E39 (1997 - 2003) > Purpose of wire connector

For the record, an enterprising soul is contemplating manufacturing stainless steel pulleys for us, which would be a godsend, given how easily the nylon ones crack:

After doing some research, I am new to the BMW community, seems like this is a common problem and though not to expensive, I am a firm believer in do things once and done. So, I have designed and built my first 303 Stainless pulley set for both the front and rear doors on my 540i. I used a bronze oil impregated bushing for the pulley to ride on for longevity. I plan on doing a write up this week and posting pics of my project.

Ive made the pulley groove slightly deeper for the cable to ride in and I've designed this as a bolt on replacement kit.

I'm thinking of doing a group buy, to sell these as kits for minimal costs per car, all four doors. Right now I want to install my set and post a write up of it and see if anyone else may want to buy the same setup and never replace your window regulator again.

Any comments are welcome, let me know if you would be interested!
thank you!

Here are some pics of the parts on my regulator.



Back side hardware:





Here you can see my layout. A threaded flange on the backside runs through the regulator's existing hole. So you will have to drill out the hardware and existing plastic pulley, I was planning on including the needed drill bit in the kit. The bronze bushing threads onto the flange thus clamping onto the regulator. Then the pulley rides on this bronze bushing. Pretty simple and easy to install.

Mega thanks for exhaustive research and description

Thanks to Bluebee and others for an exhaustive and easy to follow description of his solution to the repair of the window regulator. I also agree with his final solution: buy the cheapest repacement you can find and transfer the old motor to the new unit.
Nonetheless, I enjoyed the thread. Well done!

I bought a URO regulator for $70 and it's still going strong

I'm hoping we'll learn more about how to retension the window regulator cable based on what was posted today in this thread:
> E39 (1997 - 2003) > E39 Window motor dead

The cable has slipped out and the whole metal system that holds the door is stuck on the small black hanger
