Please HELP... I have a '91 350sd and it developed a water leak overnight. It's coming from the the a arm (or pillar) on the passenger side and it drips pretty heavily. We have been getting a lot of rain lately and I cannot figure out where it's leaking from. I have checked the outside of the car entirely and the seals around the window and doors (even cleaned the sunroof track). I tried to take the interior headboard off but after removing the visors it felt like I was ripping the leather trying to pull the headboard off. Any tips??
