I use my drivers side power window a lot, I like to have it down a bit to listen for traffic at intersections then usually back up when moving or completely open.
Lately the window started to make a Clunk sound when it started moving Up or Down.
Yesterday it got real bad, the window went part way down kind of crooked & then jammed and the door panel bulged out towards me. It took some fiddling & pulling but I got it to go back up.
Today I took off the door panel & saw 2 bolts sitting loose under the clear plastic liner.
Turns out they are from the window regulator. There are 2 bolts above (that were loose) & the 2 that fell out below holding the regulator in place.
I had to jockey the window down switch a bit to get the regulator to rotate a little inside the door so I could line up the threads to get the bolts back in.
Once I had it all lined up I took out one bolt at a time & reinstalled with blue Loctite.
So far so good!
