New tip for door rattles.
 

When I got my Boxster, there was a rattle in the passenger door when I went over bumps. I recently replaced the window regulator in the driver's door, and I gained the same rattle there. This weekend I opened up both door panels to figure out what was going on. I saw the regulator had also been replaced in the passenger door previous to my ownership, so I started to suspect the rattles had to do with the regulator. I starting moving and jiggling stuff, and I could replicate the rattle sound by moving the window regulator cables around. I added one zip tie to each door to secure the window regulator cables. Not too tight, just enough to keep them from moving too much. Rattles gone!!!!!

Thanks... Did you take pictures?
