Passenger window loose

[Rolocado]

Passenger window is able to be moved side to side if the glass is grabbed and pulled/pushed. I took the door panel off and it looks like the bolts holding the glass to the regulator are tight, but the regulator rail is moving back and forth... wtf? How does that get loose?

Time. It gets loose with time.
Maybe a dab of lock tite?

There are four 10 mm bolts holding the window regulator. Roll the window up and find the fallen bolt at the bottom of the door. Put it back on and you are good.
