Power windows stopped working

If the other window works the left contact in the switch is dirty and needs to be ckeaned

power window motors work off of a relay as well as the sunroof the four by four light flashing on and off is indication of transfer case problems this truck is about to get expensive to keep

test for power at relay and fuse hear is diagram

None of the power windows work from any of the switches ?

Start with checking the power to the driver's side power window switch, this is what is routed to the other switches ( through the window lock switch ).

The wire is a Light Blue w/ Black stripe wire, that is via the accessory delay relay ( needs to be in the accy or run or just shut off, and the door not opened yet ).



The wire could be broken in the rubber boot between the driver's door and the a-pillar ( if it tests as no power with the key in the run or accy positions.

Did you check the fuse for the stop lamps ? This is cab fuse panel F2 ( where the turn signal is fuse F13 ).

When you tested the old or new BPP ( Brake PEdal Position ) Switch, did you have power on the side from the fuse ( this is the light green w/ red stripe wire ) ?
When you pressed the brake pedal down, did you have power on the side towards the brake lamps ( this is the Light green wire ) ?

Might want to check the doors with the problem windows for a broken wire from the door to the door jam.

The window lock switch is a single circuit to all the other windows, so if there was a problem with it, none of the window controls would work ( but the driver's side would still operate them ).

The other place to check for a broken wire is the driver's side door to a-pillar harness. The circuits for the other windows run through the driver's side switch. Could be a wire in the driver's side door harness.

The other item could be the driver's side switch, the contacts will get carbon built up on them, and the windows will not operate anymore.
This is what mine looked like when the driver's side window stopped working ( lower left hand corner of the picture is the driver's side window switch, note the carbon build up on the contacts )


I would start with checking for broken wires, by metering the window switch for power.

The back passenger's window switch should be getting power & ground on the white w/ yellow stripe wire and the tan w/ light blue stripe wire.
in the "at rest" position on the driver's side switch, these are supplying ground to the power window, and power is being applied to the other side of the motor ( depending on direction of travel ).

the window relay is at fault

I am having the exact same issue. I replaced my master switch because you would have to hold the driver's window switch and wait for it to kick in. Worked 4.0 for about a week and suddenly no windows work. The lights on the switches work, but when you push on any switch in the truck the window doesn't move, but the lights dim and the heated mirror light illuminates. Both the sunroof and the rear sliding glass both work.

Did you ever find a solution for this???
