Power windows and 4wheel drive switch not working
On my 03 Super Duty crew cab 6.0 4x4 my windows do not work and the 4 wheel drive switch do nothing. They were all working one day then I let someone borrow the truck for the weekend and then they have not worked since.
SYMPTOMS
Driver door
when closed the door lock switch will work fine and the window switch lights will light up.
No windows will roll down but the driver front switch will make a buzzing sound.
Door courtesy light is dim all the time but when I hit a window switch it will get bright.
Open the door and nothing works, no switch lights, no door light, no door locks.
Passenger front door
Door lock switch always works
window switch nothing
open door and no change lock switch still works.
Rear doors are the same as passenger.
I have swapped out the switches from my 06 and have the same problems also swapped out fuse/breaker no change.
I am getting almost 12 volts through the ground wire to the switches and light.

All dc circuits must complete the loop between positive to ground to work meaning on your battery.

I figured out the 4wheel drive and that was unrelated. Thanks for the info on the ground, I will look into it and see what I come up with.
I have checked the black wire that is coming up to my window switch controls that my book says should be a ground and it has 12 volts and the coming from the switch nothing until I turn the key on then from the switch side it is giving 12 volts as well to the black wire, So when disconected and the key on I am getting power from both sides of the ground wire.
Also noticed that the passenger door curtousy light is working fine.
