Window won't roll up shut. `92 Accord Honda

The left-rear window will not roll up all the way, leaving 1" gap.
It won't go up even when gripping on the glass and pulling on it.
What should I look at to get the window to go up?

Thanks

 

When that happened on my '90, the window actuator mechanism was
broken. Specifically, it is a metal frame with some plastic guides
that control a cable driven by a little motor. One of the pieces of
plastic was broken. caused the cable to not bring the window all the
way up. Had to replace the whole actuator because the plastic piece
was not a service item, new or used. Burns me up that the service
price is controlled by a ten cent plastic part.

It is not hard to take off the door panel to check it.

By the way, when the second one broke, I didn't want to spend the
money to fix it so I took of the interior panel, blocked the window
closed and pulled the fuse on the window circuit for that window.
