Question about Buick Century
You should have 12volts on the orange wire to the switch and a good ground on the black wire. If you have power and ground at the wires you can check the switch. The blue wire will get 12volts when pressing the switch in the up position. The brown wire will get 12volts in the down position. A common problem is the wires break where the door opens and closes.
