I own (2) 2002 325i's (one for me and one for the wife). I have had 3 window regulators fail in the wife's car. Tonight one failed in my car. As you can imagine, I'm not very happy. Two of the four were covered under warranty. The last one and current one are not. I'm going to try and replace this one myself.
Based on the number of posts on this subject and the quick response by BMW service personel to point to the window regulator, I have to conclude that this is a defective part. When is BMW going to issue a recall?
My loyalty has seriously started to fade. There are been too many problems in recent months.
I appreciate the post that some gave on the do-it-yourself repair of window regulator. I'll post again to tell you all how difficult it is.
