How sync BCU to door regulator?
This is the second time in a couple of years that my drivers door window went too far down and off the bottom of the gear rack. I disassembled it and reinstalled it, then selected the window to fully up and held the switch in the up position for about 2 seconds. I then touched auto down and the window promptly went off the bottom of the gear again. Does the vehicle have an issue or am I doing something wrong?

Here's what the RAVE says.
There is no "synching". The BCU stops the motor when the window reaches its up or down position based on detecting an increased electrical load. Sounds like something physical with your window regulator. I haven't had a regulator out of my truck in years, but I'd start with inspecting the physical stop that should be hit when the window is fully down.
I hope this helps.

Hi Harv,
It has been a few years and my memory may fail me. The same window failed me twice within a one year period.
I originally replaced it with just a regulator and kept the original motor. This was when I used the plastic bottle trick pre-caution (it was a suggestion from someone else in the forum). It failed a few months later on one of the Roverlanders outings.I remember running the next couple of days with my driver's window down in dusty conditions. Not fun.
I ended getting a new (second) regulator and new motor. I found a great deal then to just get the complete set. This did the trick. I did not have much time to diagnose why first replacement regulator did not work well with the old motor. My hunch was the plastic gears in the old motor were worn.

Interesting use for the foam bar, I like it and see no problem. I "invented" the 1 litre plasic bottle trick (capped !) as a down-stop/cushion and has behaved flawless several years since.
