If you haven’t gotten the window down yet I believe you can simply unplug the window motor and apply 12v to the window motor plug. One way will try to roll it up and one way will roll it down. If memory serves I think my window motors were green & brown wires - I think power to green and ground to brown is up - power to brown and ground to green is down, either way, you’ll figure it out once your in there.

Unplugging the window motor and powering it directly bypasses the switch and should roll the window up/down, assuming there isn’t also a window motor issue.

Good luck [emoji106]
