The plastic clips holding the window in place broke and window falls down. It costs $350 to replace the $1.50 cheap plastic part.

I own a 2004 VW Passat. The window regulator went out in the back passenger side door. The window does not go down when the button is pushed. I have a friend who owns a 2002 Passat and her passenger window regulators keep breaking also. She has had them fixed several times, but the problem still exists. I have not yet fixed mine.

Sporadically the rear windows would not respond to the window up/down switch, then later without touching the switch the windows would open or close. The dealer found a cheap plastic cotter pin type instrument causing the problem. I have not had the chance to check out the repair since the dealer has my car going on 3 weeks for two other issues (transmission surge and engine light/P0101) for which they are having problems diagnosing the problem.

Rear driver side window dropped into door panel without warning approx 11/2 years ago - window regulator broken. No previous damage to door or window suggesting a potential problem. Six months ago car was taken for service because front passenger window was not opening or closing completely. Prior to checking technician suggested window regulator was going bad but claimed nothing was wrong with window upon inspection. Oct 17, 2008 same front passenger window dropped into door panel. Window regulator broken just like other. $450 min service. Volkswagen claims its bad luck not a recurring problem.
