What fuse powers the 1994 Bronco tailgate power window circuit?

Fuse position 12 in the fuse panel, a 20A circuit breaker (c.b.), hot at all times. The fuse panel details are on page 13-13.

What wire colors control the tailgate window up and down functions?

Circuit 404 P/LG (pink/light green) is 12V for UP and circuit 405 P/LB (pink/light blue) is 12V for DOWN from the master tailgate window switch. Circuit 517 BK/W feeds the key-operated tailgate window switch, and circuits 333 Y/R, 334 R/Y, and 407 T/BK run to the tailgate motor and latch switch.

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

The circuit passes through the tailgate latch switch, which is open when the tailgate is not fully closed, cutting power to the tailgate power window motor.

Where is the tailgate window circuit grounded?

Through circuit 57 BK via splice S205 to ground G201; grounds are detailed on page 10-14.

This is a page from the 1994 Ford Bronco/F-Series electrical wiring diagram manual (Bronco-specific page) covering the power tailgate window circuit. It shows power originating from fuse 12 (a 20A circuit breaker) in the fuse panel, hot at all times, feeding circuit 171 BK/W which also branches to the keyless entry (page 111-4), anti-theft (page 112-1), all-wheel drive (page 34-1), power door locks (page 110-1), and power lumbar seats (page 122-1) systems via splice S237. Circuit 517 BK/W runs through connectors C205 and C418 to the key-operated tailgate window switch (grid 151-23 E10). The dash-mounted master tailgate window switch (151-15 C9) receives 12V ACC/RUN power on circuit 400 LB/BK from splice S230 and controls the motor through circuits 404 P/LG (up) and 405 P/LB (down). The circuit runs through the tailgate latch switch (open when the tailgate is not fully closed) and connectors C428/C429 on circuits 333 Y/R, 334 R/Y, and 407 T/BK to the bi-directional tailgate power window motor (151-23 D10). Ground is at G201 via circuit 57 BK through splice S205; grounds reference page 10-14 and Section 152 covers connector/splice locations.
