Hello!

I've searched through previous posts on this board but am still a little confused as to what part(s) I may need to solve my problem. I have a 1986 300e and the driver side window comes down quite slowly and goes up even slower (often I aid the window up by pressing my palm against it and sort of helping it go up). I suppose this means that the switch is working and I believe the other windows work. Does this mean that I need to replace the power window motor (part O3050-70350 on Fastlane) ? I am not sure what the window regulator that I see numerous discussions about does... Sorry if this is a complete noob question but any help would be greatly appreciated!

Thanks,

Allister
