I brought 2 GM restoration parts, window switches. 2 of the biggest pieces of sh!!T I have ever brought. So bad, I had to take them out.
Once installed, they get stuck in the up or down position, and will burn the window motor.
This is because the center console applies pressure to the sides of the switch, to keep it in place, and the detent spring in the switch is too weak.

Luckily Ebay has the money back guarantee, and it's within 30 days. Otherwise I would have been screwed.
