The driver side front window on my E280 W124 has been getting slower and slower for sometime now. The motor seems to work fine, however when using the quick-down function, on the odd occasion the window has failed to retract and stuck.
Is there a quick way of lubricating the runners without having to remove the door panel? Any suggestions?
