Installed new rear window regulator but I'm having an issue getting it to work right
2007 328xi, passenger side rear window regulator.
Swapped out old one, no issues. Clipped the window into the new regulator as required. Window will now move up and down, but not correctly. When sending the window to the lowest point, it will NOT come back up without manual help. The motor makes a sound like something is binding it up....but if you reach in and ever so lightly pull up/help it get started it will go up fine. When it gets to the top it does not stop, it will hit the top and automatically come down half way. I must be missing something simple. Any help is much appreciated. |

When the window is down all the way, try pulling the switch up a few times momentarily, but only in the first position (not the second auto-up position.)
You'll need to re-initialize/recalibrate the anti-trap settings to get them to work properly. But I could never successfully accomplish this; I had a 06 325i E90 and replaced both rear window regulators twice and could never get the windows to open properly when they were completely down. I had to do that trick where I tap the switch up to get it to move past the seal and then it would move up completely (auto or manually.) My guess is there was too much physical resistance, maybe the glass in the frame. I sold the car before I ever got to resolve it. |

I've tried over and over to re-initialize on mine, and it still has to have the initial manual lever pull to start. I've just lived with it.

I went through this with the one I bought. Prev owner had both rear regs replaced. It was the motors. They somehow got damaged when the regulators failed. Look up my old post on this.
