'80-96 F-series/Bronco Window Circuit
IF THE IMAGE IS TOO SMALL, click it.
Where this shows the Left switch as one, there are actually 2 independent switches on the driver's door.

The door window circuit is a common (Ford) polarity-reversing circuit with 1 switch for the left motor & 2 switches for the right. The switches share power feed through the ignition switch (key-on only). On Broncos, this feed is also used for the tailgate window motor's dash switch. For the left window, the left (driver's) switch normally holds both motor wires to ground. When operated, it sends one of the wires hot, powering the motor. When operated the other way, the polarity is reversed, reversing the motor's direction. For the right window, the left (driver's) switch normally holds both motor wires to ground, and the right (passenger's) switch normally holds the motor wires to the driver's switch wires. When either is operated, it sends one of the wires hot, powering the motor. When operated the other way, the polarity is reversed, reversing the motor's direction. Neither switch is a "master" because neither will work if the other is in the opposite position. But both must make contact internally when NOT in-use for the other to work.
