there are two plugs that come off the motor, turn one of these the wrong way round (you will have to bend the clip fingers back to do this) and it wil reverse the switch and it should go down when you press up, if this happens then you have a break in the wires from the passenger side to the drivers side, the window will not work if there is a break, find whic wire by taking off both door cards and testing for continuity along the wires untill you find the broken one.
