What controls the tailgate power window on this circuit?

Two switches: the Master Tailgate Window Switch and a key-operated Tailgate Window Switch. Each directs current to the motor in the tailgate, and the direction the motor operates depends on the position of the switch or key.

Why won't the tailgate window operate when the tailgate is open?

The diagram shows a Tailgate Latch Switch that is open when the tailgate is not fully closed, interrupting the circuit until the tailgate is latched.

What kind of motor drives the tailgate window?

A bi-directional motor that will lower or raise the window depending on the position of the Tailgate Window Switch.

Where is the ground reference for this circuit?

The diagram points to 'See Grounds Page 10-9' with ground G901, using circuit 57 BK (black) wiring as the ground path.

This document is a scanned electrical wiring diagram for the power tailgate window circuit, filed for a 1996 Ford Bronco. It traces power from the fuse panel (referenced to page 13-9 of the source manual) through the master tailgate window switch, the key-operated tailgate window switch, and the tailgate latch switch (which is open when the tailgate is not fully closed), to the bi-directional tailgate power window motor. Callout boxes explain circuit operation: the master switch and the key switch each direct current to the motor in the tailgate, with the motor's direction of rotation depending on switch/key position; the motor itself is bi-directional and raises or lowers the glass accordingly. The diagram shows shared splices connecting to other circuits with manual page references: Remote/Keyless Entry (page 111-1), All-Wheel Anti-Lock Brakes (page 34-1), Power Door Locks (page 111-1), and Power Lumbar Seats (page 141-1), plus a grounds reference (page 10-9, ground G901). Circuit wire numbers and colors such as 404 P/LB, 484 P/LB, 57 BK, and LB/BK feed wires are indicated, along with several in-line connectors (C424, C425, etc.). A reader can learn the current path, switch logic, ground location, and interconnections needed to diagnose a non-working Bronco tailgate window.
