I reached up and accidentally disengaged the bug mesh lock and the thing went rolling up like mad. I think I broke the unit or caused a misalignment. When closed, there's slight vertical wiggle room on the left side, like it's off it's track, but the right side fits snugly with no vertical play. I can open and close, but I have to help guide it on the left, either while opening or closing, else or it gets stuck.

Anyone have this happen to them?

 

I bought my used LR3 like this, knew something wasn't right. If you pull the thing out half way, rotate it (yeah, don't worry.. it should be okay haha) so one corner is at the front and other is at the middle-ish.. you can tuck each tab into the channel again. Try to boost yourself up off the seat and you'll see the correct channel for them to slide in. When mine was acting like yours, it wasn't in any channel at all - just kinda flopping around free near the glass.

It should also lock into place better now and retract more slowly.

 

DONE! that was the e-a-s-i-e-s-t fix on this truck ever. results are exactly as described. thank you.
