On my dad's 90 vert, the 1/4 windows seem to be stuck and won't go down. When you push the button, you can hear the motor going, but the windows won't move. Anybody else ever have this problem and/or know how to fix it? Thanks.
The window motors have plastic ball bearings in the surrounding the drive gear. If you do indeed hear the motors running and the windows don't operate, either the plastic bearings are worn out or the motor has somehow come loose from the regulator, but the first is more likely vs. the last.
