Thanks!
I took mine apart and here's where we are:
* Electronics work well
* motor moves the arms up and down ok
* Cleaned out the groove the wheels sit in (and greased them)
* replaced the sash
* I assume my torsion bar is not right which is why the tailgate feels heavy (I looked at others and they are not this heavy)
Yes the 'sash' is the metal tray that holds the window. LMC refers to it this way.
Mine had bent in the middle (kinda rusty) AND it was no longer attached to the window. So it would allow the window to get off the 'sash' since it was no longer flat.
There is also some rubber strip that goes in the sash and holds the window firmly (it's just a strip of rubber).
I ordered a sash from LMC truck ($70?) felt expensive, but worth it to have a working rear window again.
It was longer than stock and so I trimmed it up, installed it and now it works great again! Hope this helps someone else!
New Sash is too long:
Old Compared to New
New one looks a little better!
