Hey guys- 71 2002..


was rolling down the passenger window- heard a clunk and it stayed down.


First time taking off panels etc and I have the regulator out- and here’s what it looks like - the part on the bottom of the first image was connected to the lower window mechanism and would still roll within it- but the window wouldn’t move up or down. Help!

The pin that broke is available as a spare part from Mercedes Benz; and that pot metal pin that holds the concentric spring in place (it's in the center of the sector gear in your first picture) isn't long for this world.  It's gonna pull out and break.  


I did a column on repairing that center pin, and it has the M-B part number; PM me and I'll send you a copy.

Same scenario... was driving and heard a clunk in the drivers door followed by something sliding around in the door. Upon later investigation, found the tension spring at the bottom of the door and the pin (that the outer spring coil hooks to) MIA.


Is this a “regulator out” job to replace the pin and spring? Or are there any tricks to perform with repair with the regulator in-situ? I expect the former, but thought I ask before going down that road. TIA!
