Window problem: Regulator, Clips or Motor

[440films]

I have a window that has some issues but I'm not 100% sure what's going on. I've been reeding all the threads on window regulators for years now and I always anticipated my X5 would have a failure. Well it happened this weekend.

My buddy and I were golfing and after the round I started the car to get the air going because it was 100 degrees outside. I also rolled down the windows. Well, you can guess what happened, my buddy closed the door with the window down. The window won't move up more than an inch.

I removed the door panel and saw that one of the clips that holds the window was a little askew. I corrected it in to position with my hand only. I was able to push the door up and the window will go. But if I roll it to the bottom it will get stuck again.

The motor does seem a little sluggish when rolling up on both the driver and passenger windows compared to the rear windows. Not awful but noticeable.

So I'm wondering if I need to replace to regulator, the clips or the motor. Any help is appreciated.
