I have a 1998 f-150 and the driver side power window will not go down but will go up I have already changed the motor and the switch and has still not fixed the problem.

Rear Passenger Power Window Operation
The rear passenger power window switches receive battery voltage through the window lockout control circuit if the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through normally closed up and down contacts of both the rear passenger power window switches and the driver power window switch. When the either rear passenger power window switch is placed in the down position, the power window motor down control circuit is switched to 12 volts and is applied to the down side of the rear passenger power window motor. Since the other side of the rear passenger power motor is connected to ground through the normally closed up contacts of both the rear passenger and driver power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the driver power window switch.
Did you try pushing the lock out switch on the drivers master switch ?
the red/yellow and red/blue are the power/ground wires to the motor. You should get power on one and ground on the other when you operate the switch. The polarity should reverse when you operate the other direction. The blue wire is a pulsar wire to give motor feedback to the switch.
If the motor works when you apply power and ground directly to it the problem has to lie in the wiring or switch. I know you replaced the switch already but i would start with verifying that the switch is providing power and ground to the appropriate wires to the drivers window motor. You can check it at the motor first, if you don't have power there, check it at the switch. If you have power and ground at the switch but not at the window motor look for a broken wire. If you have power and ground at the window motor connector, yet the motor still doesn't work, do a voltage drop test to determine if there is excessive resistance in a connection or wire somewhere in the circuit.
I beleive you need to change the Power Window Switches Module in the drivers side door panel, as these connections are interlinked within this module and it is usually the first part that fails. Especially that you already changed the switches & motor in the passenger door and it still does not work. Once you remove the dual switch module in the driver's side door, you will understand what I mean. Plus it is really easy to access. Good luck! I have the same model, Claude
Try the fuse. The switch may be faulty so check by removing the inner door panel and connecting a 12v battery via two wires to the motor that winds the window up and down. If it goes up and down it's probably the switch which may just need a clean on the terminals.
The driver side window switch is the master switch, the power or input to either roll the window up or down goes thru that switch. Double check all the connections on the back of the driver side window switch are good. With a DVOM you can also check to see if 12v are even getting to the master switch in the first place. If you aren't even getting power to the main power window switch you could've blown the power window fuse.
The same thing happened to my 1999 JMC Jimmy recently. I believe the problem is that your power window motor has most likely gone out or is starting to go out. The motor will need replaced. They are pretty expensive new. I went to a junkyard and got one for around 15 dollars. When mine went bad, I had rolled my window down about three or four inches and it stuck there. I took my door panel off and tapped on the motor while holding up on the window switch and got it to go up after a few minutes. I am replacing my motor today, I'll leave an update here about the outcome when I finish the job. I hope this information helps you.
