The electric rear sliding window does not work. Where is the fuse located? 2005 Ford F 150 Lariat Crew cab.

If the power windows still work, it is not a fuse issue, they share the same fuse ( F401 form the accessory delay relay )

Either the switch or the motor is the cause.

When you press the button to the close direction ( with the window closed ) do the lights dim ( headlamp / interior lamps ) ?
If they do, the window is getting power in that direction, so it could be the switch for the open direction or the motor, or something in the track.

If you pull down the overhead console ( the non rail one is open the sun glass compartment, and pull down on each rear corner, it is held up with spring clips ) the wires to the slider are Red w/ yellow stripe and yellow w/ light blue stripe.
If you apply power to these wires, one direction is open, the reverse is close. Test direct to the wires to know if the slider motor is the issue or the switch.


Check the entire track for obstructions

To get the slider motor, you need to remove the rear seat back
