I have a 2019 f150 xlt and the issue I’m having is the driver side window switch. I have power and can roll down my rear windows both sides and I have ability to lock them. I don’t have power to the driver window or front passenger window.


I also don’t have power to the mirrors. I’ve taken the whole switch apart and check the fuses and can’t find anything.

 

My comments are based on 2007 F-150 window switch diagrams and my recent work on a 2000 Mercury. Your set up should be similar.
As you said you have power to the master control switch as evidenced by the functionality of the rear windows. All power to the master control switch comes through the same fuse.
The individual switches (ie driver's window etc) have three positions, Up, Down and Neutral. In the neutral position no power is being sent to the window motor and up and down requires manipulation of the switch. Assuming switch is accessible. To test that the switch is ok turn it over and touch one lead to switch output (either one) and the other to ground while manipulating the switch back and forth (key needs to be ON), you should see ~12 volts. Do same test with the other output and again you should see 12 volts. If you don't see about 12 volts then test one of the other good switches to confirm that we have a good test method.
BTW in my 2000 Mercury the output from the switch then traveled through a module before actually going to the motor and this complicated my testing since I had the module disconnected for access to the window regulator replacement I was doing. Reconnected module and all was well.
Lets us know what you find.
