edit: after re-reading the original post I'm suspecting that you have pins (1 and 2) reversed in the connector. There are two switches and pin 2 is common to both. I believe that you have pin 2 in the pin 1 spot. That way one side will test right but the other will not. If this is off also make sure that you have 1 and 3 correct according to the diagram. Once you have pin 2 right you will be able to test 1 and 3 for proper orientation.
