I always look to the Archive with my continuing newbe learning curve.
But my best choice key words don't always give best answers.
Can someone point me to Archive references for  these two current issues:

82' diesel 1.6 na, camper.

"Window   Roll-up  Jumps Track"
Driver's door window nylon guide pops off the door center track and
glass does not roll up. Door panel off and I've restored it, wired a
speaker. ready to seal and button up.
But,  glass has derailed from track the 3rd time now.    How can guide
be fix but good?
.
and

"Dash removal projects"
I am planning to remove the dash this fall to restore heat control
levers, replace heat fan, add gauges and radio  -- and -- What Else?
I need the recommended open dash  projects, upgrades  -  Recommended
and illustrated procedures and parts.

I have the Bentley.
