Thanks David for the reply. Can you or Southern son, or anyone for that matter help me with where to start looking for this vacuum problem? I am an amateur mechanic, and I do mean amateur...but I love working on my mercedes....Any help is appreciated on this AC problem.
The sunroof, the motor works fine on the sunroof, and it doesnt slow down, but it gets stuck at the same spot every time, and you have to reverse and then go forward again and it closes fine....when you close it completely, from the inside, the corner flap raises as if it is popping up,(could it be off track?), and when you hit the pop up button, it doesnt do anything(not even noise).
I will try to grease the rails this weekend to see if that alleviates the problem.
I will also attempt to take the door panel to investigate the window.
Thanks,
