Graham,

I agree - hence the name of this thread! I can't figure out what's going on...I am checking voltage at the 2 bottom screws, using the top screw as the ground (I also used a variety of other ground connections with the same result).

To reiterate: when I depress and hold the window switch - in either the up or down position, I am getting 0 volts on both wires on the door connector.
