Yeah, we have one window (next to the recliners) that the little tiny plastic pins on the end of the latches that engage in the window track have broken off. I have not yet found the correct replacement window latches to repair it. You have to be careful to hold the latches firmly in when opening and closing the window, don't let the latches go out when raising or lowering the window, it will snap the tiny little plastic pins that engage in the track right off.
There are a lot of window repair latches out there when I googled it, but none of the specific type we need. I have not yet connected Lippert directly to see if they have the specific latches we need.
One person did post on the forum how to replace the window latches without taking the window glass frame out, but that was a long time ago. As I recall, This person got replacement latches from Lippert, used a Dremel tool to remove the small raised ridge on the window glass frame where the latch is located, then removed the screw that holds the latch in place, then slid the latch out of the track to R&R, and put the screw back in, the poster said this worked for him .
We only have one window so far that the latch pins are broken on both sides, if we want to open that window, We'll use a wooden spoon to hold it up!
