hey guys, just installing front power windows in my vs wagon. wiring was all there just plug n play. the passenger door works fine up and down, but the drivers will only go up. ive tested it with a battery hooked up and it works fine(its new anyway).

any ideas?

If the window goes up ok but wont go down It is probably something to do with the bcm or the up switch in the console.The circuitry to the window must be ok if it is going up as its a simple polarity swap to change direction.
It doesnt use the bcms electronics to go up...just a set of contacts on a external relay near the steering wheel...see if that relay clicks when you try to drive it down...it should if the bcm is wired properly...there are 4 wires that go to the bcm for the power windows ...check to see if you have 12v on the green /black wire in terminal a8 of the bcm when you operate the switch.
