I have a 2004 Supercrew. Recently I was having intermitent problems where all power windows would not roll down or roll up. Now no power window switch on any door will work (luckily my windows are up), telling me it's something centralized. I checked the fuse and it is good, and even replaced the driver side power window switch but nothing. There doesn't seem to be a relay for the windows, or is there? Has anyone had this problem before? What else can I check? Thanks!

 

mm,

Did you use a meter or continuity tester to check the fuse? You can not always tell a bad fuse from a good one by just looking. Been there done that.

Get a wiring schematic. Have you checked for voltage at the switch? If no voltage at switch, work your way back. Yea I know easier said than done.

Below is a continuity tester I assembled from junk I had around the house the most expensive part was the 9v battery. The best part about this is you do not have to watch your ohm meter, just listen.

 

Geez T-M-P..neat rig..thanks for the idea..sorry mm, no info on the windows but I think you're on to something with the centeralized thing...by all means RE check the fuse...good luck..P+J

 

Did you figure out what the problem was? I have an 05 f150 XLT supercab. Everything works great on the truck except the windows and the switch for adjusting the side mirrors. The windows were working occasionally but now only work when the weather is cold, around 70 and below. The door locks were great on both doors but the window switches on all doors do not work, and the lights on the switches do not work either. When the windows are working, the lights on the switches will work. I took apart the drivers side window switch and cleaned it but that didn't do anything. I also checked the rubber tubing from the driver door to the truck to look for exposed wires but everything looked good. Any help would be great, thanks.

 

I can't explain why it only works at certain temps. My power windows were dead all together. I had to cut open the rubber tubing between the driver door and main cab, and found a severed wire. I re-spliced it and it worked! All the windows work now.
