1. If your window is falling out of the channels it may not be
the channel itself that's bad; two other things can happen:
- tensioner rod is loose. This is a bent rod that wraps around
the rear channel at the end and is used to kind of bind the
whole assembly together. Check that it hasn't worked loose
at either end.
- Rivets holding the channel to its brackets have become loose
over time. if the channel wiggles independently of the
brackets, this is your problem. Drill the rivets out and
replace them.
2. If you do buy new channels, test fit them first with the door
disassembled to determine the correct length to cut off and
the best mount position for the brackets. Just copying the
original position and length can be unsatisfactory.
