If the passenger window does not work I would suspect the window motor. this would be with using the master and door specific operating switches. on the seats both not working I would check for fuses.

I was going to suggest looking for fusible links somewhere in the hot power line for those circuits. For the window - a corroded switch could cause it to stop working also.

My two cents. Hope you get it fixed.

so ever time you operate your vehicle you operate the seats and passenger side window ?

I would get a volt meter and start checking fuses and also the feed to the window motor when the switch is hit.

Instead of doing that why not just disconnect the battery for ten minutes?

For some reason it will not usually work with just battery disconnected I tried it and it was a no go, there is a right and left ecm fuse and it needs to reprogram but not loose total power to computer

@badss98, I might buy your fuse theory if you were talking about the Body Control Module (BCM) and not the Powertrain Control Module (PCM). The PCM should not impact things like windows, or seat (maybe the seat of your pants, but not the seat you sit in).

I don't have a wiring diagram for that truck, but it probably has a fuse panel inside the ruck. The internal fuse panel usually controls the "creature comforts" things in the cab. This panel is fused from a large (size and amperage) fuse in the main panel under the hood. Check the big fuse.

If you continue to have problems. Check the circuit breakers in the panel on the drivers side of the dash. If you have memory power seats, There is a whole list of things that go wrong. The most common is the module under the seat has a massive "brain-fart" and will need to be replaced.
