Window is in a bad state.
A couple weeks ago I put down my driver’s side window and it never went back up. I was told it would get stuck down occasionally when I bought the car and given its age I should have suspected it was time for the windows to stop working anyways. Doing some research on the internet yielded me some answers. Apparently, the power window switch goes bad in Volvos of this vintage so that’s the first place to look instead of taking the door apart to look at the motor and regulator. Lucky for me, it was just the switch. The switch can be disassembled and cleaned to make it work again! I made a video documenting the task below.
