Hi. I have a 2006 535xi. About 2 weeks ago the back right passenger window started having this issue. When I try to close it, it will go all the way up then slide back about 1/4 down. The same thing started happening to the sunroof that same day. I went to the mechanic and got the battery replaced and the day after that (I didnt use my car the day before) the front passenger window stopped working completely. Are those issues related? What could the problem be.

Thanks.

 

Same problem with my e60 as well. Right Rear window.
