All 4 of my power windows in my 04 Ford Explorer XLT are not working. I was not having any problems with them. Try to roll down my window the other day and none of them would even budge or make a noise. I tried all 4 doors and nothing. Any suggestions? Thanks.

I take your comment of saying, ":I tried all four doors" to mean you tried the switch on each door, not just from the drivers seat.

One concern I have is CHILD SAFETY LOCKS. Is it possible that you have these, and that they have been engaged and turned on?

If there are no child safety locks having been engaged, and considering how all of the windows are acting up all at once, Not just this one or that one not working,

It could very well be that your power window fuse has burnt out and needs to be replaced. It is also possible that your vehicles battery is dying and just too weak.

So, I would first recommend checking all your fueses as well as any Maxi fuses under the hood, not just the fuses panels under the dash... If your'e lucky a fuse may be sitting tilted in the socket or simply burning out.

It would be helpful to know if anything has been done to alter the vehicles wiring, such as a security alarm or a new stereo, speakers, amplifier or anything else recently being installed, as it may have been done improperly. That is to say if this is a recent problem that has just started to happen.

There are many who may suggest that you have a short in your wiring... That may be true and can be a long tedious task to track down and isolate...

So, I strongly urge you to consider a NEW BATTERY. Clean Battery Cables, making sure there is no corrosion (That could cause all these things) And be sure to check all fuses. That means pulling them and visially inspecting them to make sure they are not burnt or broken.

On that note, I have replaced fuses that looked fine and the problems went away... Keep in mind how some if not many or even all of those are possibly 7 years old... They are a cheap fix... Even if you replaced each and everyone.

Sometimes I've known those who had a Keyfob (remote) whereas the battery in it was bad even though it may or may not be locking, unlocking or arming the vehicle, Consider changing the battery in it at a minimum of once a year. I think it is recommended every 6 months. But that is usually dependant on eachs persons use.

If all the fuses are good and you have installed a new battery and these things are not working, you could be looking at the actual switch or possibly a window lift motor going out and even the door lock switch burning out. Some things you can have tested and others are typically cheap enough to replace. But I would investigate looking into these, having them tested, prior to chasing a fantom wire short, which may or may not be present at all...

Even buying a second hand part at a U-pull it can be quicker, cheaper and easier verification process than chasing a short which may not be...

Good Luck to you and Happy Motoring...

Sounds like you have a broken wire or two in the rubber conduit between the driver's door and the door jamb. Very common issue. Power to all 4 windows goes through the master switch in the driver door.

Blown fuse. check all your fuses.
