1998 Ford f-150 Passender side window issues:

I'll explain. The motor in the doors is a DC motor. There is a positive side and a negative side to the electrical connection on the motor. If you hook up the motor one way, the motor turns to the left, causing the window to go up. If you reverse the polarity on the motor (switch the wire connections) the motor will run in reverse causing the window to go down. Usually power is supplied to other doors from the drivers side, but not always. If you want to check before throwing money at the problem, use a multi-meter and check for voltage being supplied to door switches. If you want to check the motor, remove it from the door and apply 12 volts to the electrical connection points on the motor. If it does not turn, it's bad.
