SOURCE: 1999 f150 turn signals and brake lights out. High mast still work

The signal lights work through a relay but the brake lights work through the signal switch, if both are out I think you'll find the problem is the signal switch.

SOURCE: Rear turn signals and brake lights won't work

Probably the turn signal switch assembly. This is a common problem with the older Fords. The switch is a self contained unit at a cost of about $100.00.

SOURCE: REAR TURN SIGNALS WORK BUT MY BRAKE LIGHTS DONT

Replace the turn signal switch. If you want to prove this have someone stand behind the car with your foot on the brake. Then wiggle the turn signal lever. The brake lights should blink. This is a real common problem with W body. I have replaced two on my cutlass plus tons more at my shop.

SOURCE: turn signals dont work bulbs/fuses are good.

check to see if the emergency flashers work if they do its its either a wiring problem, bulb, or socket the bulb fits in. if it does not work than the flasher is the problem. it is located underdash on driver side in the kick panel( to left of the brake pedal) it is a blue or grey sguare relay looking plug. if it is factory flasher it will say flasher with the part # on it. it should also say toyota on it. good luck

SOURCE: I have a 1997 Ford F150 4x4 Supercab Stepside with

It is a possible option that the relays for the Stop / Turn are having an issue or the fuse in the Engine Mini panel is blown ( page 142 of the 1997 owners manual )

On the 1997/98 MY this is in the aux relay box in between the Engine Compartment fuse panel and the engine mini fuse panel.

The output of the MFS ( Multifunction switch ) triggers the relays, to use the trailer tow fuse to operate the trailer lamps. The fuse to supply power to the Normally Open contacts on the trailer relays should be hot at all times. You can verify this with the diagram below by metering from pin #3 to pin # 2 [ground for coil] or to another known ground.

These are 1/2 size Ford ISO relays, and can be jumpered to make testing easier ( and with this diagram you can bench test them with a meter to check resistance over the Normally Open contacts, when applying power and ground to the coil ).

I am not 100% sure on the 97/98 MY F-150 about the location of this connector, but the 99-03 have all the wires to the rear of the truck via a connector along the driver's side frame rail, that you can check for ( easiest with the spare lowered )

Start with the Fuse in the Engine Mini panel, to see if the 20A fuse is good and work back towards the trailer tow adapter via the relays. I am going with the obvious blown fuse for the Stop/Turn lamps for the trailer.

I put new bulbs but when i press the brake light they dont turn on and i dont have a manual for fuses.


The brake light switch located above the brake pedal may be faulty or needs adjustment.

Turn signals are not working


It sounds to me like you have a short somewhere in your wiring. I would first replace the turn signal switch and go from there. Have you added trailer brakes or anything which may have spliced into any wiring if so I would have anything that was added disconnected and then I would check lights, signals afterwards
