Rear electric window gremlin

[itscoo2pyopants]

i had the same problem on my X5. I took the door panel apart and disconnected the motor from the window regulator. the motor will roll up, but not down. I tried using a new motor, same results. i tried using a new switch, same results. the weird thing is sometimes it works, sometimes it doesn't. I'm beginning to think it has something to do with the GM5 module itself. it only effects the rear drivers side window.

i also hear a "clicking" in the fuse panel in the glove-box every time I use the switch so it is not a fuse.

let me know if you figure it out. i haven't bothered to investigate further as I rarely use the rear windows.
