Project E36 M3 - Replacing the Window Motor and Regulator October 04 2013
The officer didn't seem pleased as I tried to talk to him through the sunroof. "I don't mean to be rude, but my window doesn't roll down," I explained. "Can I open my door instead?" "NO," was his emphatic response. Apparently, he really didn't like open doors. He walked around to the passenger side of the car. Sensing the tension of the moment, I choose not to be a smart ass and lie about the passenger window not being able to roll down either. A few minutes later, I took my ticket through the fully functional passenger side window and continued on my merry way.
The defunct window motor on our E36 M3 was making it difficult to speak with the friendly local law enforcement officers, and paying tolls with coins was awkward. It was time to replace the window motor. A lot of people go ahead and replace the window regulator at the same time, since it is easy to mess it up when drilling out the rivets.
