🚗 Premium Power Window Regulator without Motor for BMW E39 525i 528i 530i 540i M5 2000-2003 Rear Right Passenger Side Review

This part had to be replaced twice free of charge under warranty but the time and labor required to replace this part is annoying. Now I will buy another one.

Immediately after installing it I realized this was probably a bug. Unlike all other windows, which close very softly/softly, this one crashes into the end of the stroke with an audible pop. I knew it probably wouldn't last very long and sure enough, 11 months later it's dead and needs replacing.

Fits perfectly. The problem is with the bottom pulley that the motor attaches to, the cable gets tangled and you can't unhook it. This will also break the wire at the top of the pulley. The sad part is I've only rolled down this window a couple of times. I'm not saying you need to buy a genuine BMW part, but don't buy this one.

I'm so sorry I tried to save some money and ended up using those horrible controls. I changed 4 of them because they break every two months but they have always been under warranty. I even epoxyed the mistake on the last two, but the cables might just be too tight. This could be a great buy if they can find a way to keep the cables connected. Do yourself a favor and go OEM!

These regulators work the same as the factory regulators. If your e39's rear window doesn't rise and fall but you can still hear the engines running, this is your best bet! I was able to put the factory engines on the new tracks without any problems. However, I had to run to the hardware store to get 4 M6x1.0 screws to attach the bottom of the controller to the door as the factory didn't use mounting screws like these, no big deal. A few bucks later and my windows were working great again!
