Power window lost home?, Reliably stops 1.5" from top Options

[HectortheRican]

Can this happen, guys?

The driver side window otherwise works fine. It's not off its track. It rolls all the way down and almost all the way back up reliably - it just stops 1.5" from the top.
Could the motor have lost its 'zero' somehow?

Edit: At it's final level, 1.5" away from the top, it behaves exactly like it would if it were all the way up. Upon toggling the switch up, it makes no effort to move. Not sluggish or anything.

Frost King FV516 makes a good replacement vapor barrier and has some sound blocking/heat blocking properties. You can peel and stick it multiple times and it stays stuck over a very wide temperature range, I've been using it to seal my door panels for a couple years. It seals out some road noise, seals out drafts really well (good if you're in a cold climate), adds R3 insulation (good for rejecting solar gain/keeping heat in the car), and can seal the door cavity to help isolate the speaker from it's back wave or whatever and make them sound better.
