check drivers door for window lock button,also check wiring between door and jam for bare/shorted wire

Check the fuse first then with the interior lights push the window button. If the light dim the window motor is bad, if nothing happens then there is a switch problem. I'm betting on the motor.

First check would be for blown fuses. Next i would check for a good power and ground at the drivers door switch. If you find a bad power or ground at the switch, trace it back and look for a broken wire. Most likely place to find the wire would be in the drivers door jam. If your power and ground check out ok, and the switch isn't providing power to the window motor and door locks when pressed, then the switch is bad.

Check the wires & fuses but it's most likely the master window switch. This is the one at the drivers door.

its very common for the contacts in the window switch to go bad no more than it cost to fix just get one and yes its common for the regulator and motor to go bad your problems in the switch

Before you replace anything, inspect the connector pins in both the driver's door switch and the passenger door switch. If you don't find any problem with these connector pins, replace the driver's door control switch.

depending on what year truck it is, there is a 40-60amp maxi fuse in the underhood fuse block that can also blow, the harnesses get stuck on the backside of the seat tracks and blow the underhood fuses.

I'm assuming you have power windows, If the switch dies the window won't work, even if one switch is ok the window still wont work. The cheapest way to determine which one it is is to use the lock switches it place of the passenger side window switch. Replace them one at a time to determine which one it is.Once you have it working just replace the faulty switch with a new one.
hope this helps!
