Hi
I have an 06 X5 with 63k miles. Just recently started experiencing driver window getting stuck when lowered to the bottom. I ended up removing the door panel and examining the regulator and didn't notice anything wrong. After lifting manually from the bottom and using the window button, I managed to get it up. I noticed its sluggish rolling up now, not as smooth as the other windows. My question is, is the regulator on its way out or the motor. If its the regulator, does anyone know have a tutorial on how to replace (never did it) and same goes for the motor. Alternatively, I am prepared to pay someone to replace either, if I remove and install the panel myself. Btw I am in central NJ.

Thanks in advance for all your help
