Front driver's window. Yesterday it went up with the power button; however, it went up tilting forward or down at the leading edge - not straight. I grabbed the glass, held it level and the power button lifted it fine.

So it obviously is not the sliding jaw. Sounds more like the sliding jaw is no longer sliding - so it pushes up the back of the window instead of sliding as the window goes up.

Anyone experienced this problem? Seems to go down fine but I hesitate to check.

Thx.
