450SEL LH front window not working
« on: 14 December 2020, 06:40 PM »
Hi all, new to these forums and registered because i love the wealth of info on here.

I have two questions; first is how do i access the library trouble shooting articles with pics etc for various issues, i can't find the link.

The other question is the window mentioned above will not go up or down, i have checked the switch and it's fine and the terminal block on the motor has power to it so it's most likely a shit power window motor. How do i find a good article on how to replace it with pics in the library?

Thanks in advance

Welcome. The tech part of the site is located at
There's all kinds of service manuals linked from there.

As for the window, don't dismiss the motor immediately - the lifter could be seized as well if not lubricated in a long time.
