Thanks for this write up.

My driver's side is now acting funky. The regulator works, but when closing it all the way, it doesn't raise then stop/seal (normal behavior). It oscillates around 1/4" between slightly open and fully sealed when trying to close it. Like it's trying to latch onto the last spline of the gear but not catching it fully.

Is that fixable or am I looking at a new window regulator?
