Help! Is it window regulator or motor or switch

So my driver side window stuck down position and won't roll up. I managed to removed the panel but now how do I know which is broken?
Is it the motor? the regulator?

When I turn the switch, I hear a click at around the motor area ... that is all I can tell.

Also did I damage the black lock stick when I removed the door panel? Now it stays up and won't go down? (See picture below).

The black lock stick here won't go back down. It was in the up (unlock position) when I removed the panel so I don't know if it got damaged.

Never mind. I think it's the switch. I used my key to roll up the window and it worked. So thankfully it's the switch because the regulator would have been a PITA to replace.

Is there a way to fix the switch? I notice theres no clicking when i go to roll up my window from the switch. Is it just popped off? Fixable? Or i have to replace it?

I'm sure someone has sprayed their switch out and cleaned it from the Dr. Pepper that spilled in it...not that bad to do...or to just replace the switch.

That said, you could swap with another switch first and test your theory...could be a wire issue too.
