Apparently after an A/B servicing on my 99 ML320, the tech must have OVER-lubed the window track on the driver's side. Now, months later when I raise the window from the lowered position, I get a big smeared mess of lube as the window travels upward. It used to be a thin line of gunk, but now it has increased in area! I have to get out the lighter fluid (or WD-40, or whatever else I have) to get the crap off the window.

Is there any good way of getting this solved without having to remove the door panel? Otherwise, I will have to reread the "ML door panel removal" thread...
