Dues box ? do you mean fuse box . There are fuses for the power windows in the under hood fuse / relay box ! F1.62 30amp fuse an there is a relay in the CJB - central junction block ,located under the driver side dash panel . Accessory delay relay , first one top left in the fuse box. That's a good place to start ! what if fuse an relay are good ? then what ? do you know how to use a DVOM - digital volt ohm meter ? Do any of your windows work ? The best place to start is the drivers door window switch ! All power to all windows come through that switch .The lite blue with black stripe wire is power wire at the switch !

Before you do this you might want to try fresh gear lube. On Ford products they use a synthetic additive in the rear and not in the front 4x4 axle.
The next thing would be to determine if it is a wheel bearing or a pinion bearing. You have to pull the axles and eliminate them as the problem. You might get lucky and not need to do the pinion.
The technical part of shimming the pinion gears with replacing the pinion bearing is about the worst part of the job. You won't know about the gears until you see them. You will need extra shims on hand.
It is a moderate job for two people. If you have all the parts it can be done in a day.

Power windows stopped working. Have checked the fuses and they are fine. All other systems are functioning. Any thoughts?
