1987 Ford Taurus Wagon, no tail lights or turn signals

Check Fuses and Relays, but this has a GEM (general electronics module). You may need and auto-electrician as nothing covers brake lights, but that may be a fault with the brake light switch.

2012 Ford Escape fuse box diagram - StartMyCar

https://www.startmycar.com > Escape > Fuse box
The 2012 Ford Escape has 2 different fuse boxes: ... Brake Shift Interlock (BSI), Passenger compartment fuse panel. Fuse MINI ... Turn signals, Stop lamps.

Tail lights are on fuse 15.

its likely the turn signal switch (multi function switch) if the hi-mount still works,

Turn signals share a fuse with brake lamps: cavity #1, 15 amps (light blue)

You will have to check there is an output voltage from the switch ( suspect plug connector) . If you say the fuses are ok then you will have to try either a relay or fuse box connector . Good luck

It is the light box. You know the pulley you use to turn lights on and off??? that goes bad all the time. Replace that and your gold.

You need to replace the turn signal switch mechanism in the steering column.The turn signal switch is shorted out and causing the problem.
