I have a 2004 F350 Lariat crew cab. The front passenger power window will go down but not up. Checked the connector at the motor with a test light and there was juice on each wire depending on which way the switch was thrown. Figured the motor was bad, so I installed a new one but nothing changed. I did notice the window would go down, down only not up, when you used the master switch in the driver's door. It does nothing using the switch in the passengers door. Tried to disassemble the pass door switch and noticed it has a circuit board and is not a simple switch. Could the problem be in either the master switch or the pass door switch? Thought for sure a motor would fix the problem since it was getting current.
