Passenger window won't function from the drivers door switch. Installed a new drivers door switch and it still doesn't work. The passenger window works fine from the passenger door switch.

 

I would check wiring in the boots between the door and the cab and fuses.

 

I second that-it is not uncommon for wires to become pinched/worn from opening and closing the door over time.

 

i had the exact same problem on mine as well.
broken wire in the boot. took longer to find the frayed wire than to repair.
easy fix when found.

 

Thanks all, will check that and update.

 

@projump @airm4n @Flatbed79F250 and @mjlewis are all probably dead on - broken wire between drivers door switch and passenger door switch somewhere. Most likely, but not absolutely, in the boot on drivers door. I am temporarily placing a copy of the wiring diagram out of the Factory Service Manual for a 2005 F150 (it should be same as yours) on my server. www.devoll.com/Public/F150-window-wiring.pdf You should be able to print it out or save it to your computer.


If the window goes up / down from the passenger side switch - the Yellow/Lt Green must be in tact. Check for 12 v at pin 3 on the passenger door switch when you operate the driver's door switch (to eliminate the switch). If 12 v gets there from the drivers door switch, replace passenger door switch. If not - I'd try to find the "Tan/Light Blue" wire in the drivers door boot (most likely trouble spot). If it is not obviously damaged/broken, use a straight pin through it and check for 12 volts when you work the drivers door switch for the passenger window. You HAVE TO get 12 volts to pin 3 on the passenger door switch for it to go down.


Hope this helps
