my windows won't roll down at all, I'm not getting power to the actual switches. I fixed a few wires that broke at the hinge of the door and checked the continuity on the harness inside the door and everything is good. The power mirrors work and the power locks work but not the windows. I checked fuse 401 and the fuse is fine. My question is, is there any other fuses that I can check for the power windows, im not having any luck finding a wire diagram online at all. Thank you guys for your time.

If you have checked all the switches and wires and dont have power at the switches I would think it has to be a fuse. We need details, year, cab style, trim level etc. Thanks.

Oops.. sorry 2007 f150 lxt extended cab

Is there any ither fuse I should check other than 401, the 30a breaker

Okay and I re-read your first post. You said you had continuity in the door harness but not the switch. Is there power at the plug of the power window harness?

Here's a wiring diagram for windows on an '05. I don't think there would be major differences except maybe some wire colors or something.

perhaps this will help.

The only power I have to the harness is for the power mirror and the lock/unlock, nothing for the windows

You mentioned fuse 401 in your original post so I'm presuming the linked 2005 diagram is relatively representative.


I would use a test light probe and check for power on both sides of fuse 401. The fuse may be fine, but if you don't have 12 volts there a good fuse ain't gonna' help. Right after that I'd be checking all the pins of the relay at the top of the diagram. It is one thing that can KILL ALL the windows if its contacts are bad/corroded or if its coil is open or a bad wire from pin 21 to the Instrument cluster is 'open'.

I have power to both sides of 401 :/

I ran a wire from 401 to the switch and the windows work, I'm guessing that there's a short somewhere in between there,I'm just going to run a new wire to the door, I thinks that's my only option
