Question about Ford F-150
Thanks for choosing FixYa and welcome to the site. Since all power aspects appear normal, this would lead me to believe that it is your tract bar inside the door. It may be broken or just off track. This would be what pushes the window up. In order to get to it, you will need to take off your door panel. Remove any plastic or foam within the door. This bar hugs the main bottom of the engine and pushes the window up. Like I said, the window is either off tract from the bar or it is broken.

Since the Window is going down, but not up, I would suspect the switch has gone bad. Refer to the following wiring diagram for the wires to check and use a multimeter to test the switch.

Given what you have replaced, it sounds to me like your window is off track or the track may have a rivet or two busted on it to the point the window will not track up properly. Windows always go down easier because of gravity. The other thing that could be just as much responsible is the regulator. You need to pull the door panel to inspect either. I can assure you one or the other or both are the culprit.

Possible problem in the windows switch contact at UP side. After to of up and down wears on those contacts. If up or down side in its
relaxed position is bent or sagging, and not making contact to ground,
that 12 volts you read there will never pass through the motor. Nee a new driver switch.
Hard, but possible, bad alignement frame window? Test it and keep us updated.
