Brake Lights not working

[Seajumper]

New 2016 Windsport 34J Ford brake lights are not working, but turn signals and hazards are working. Any suggestions?

I don't know if you have a 450 or a 350 but for the 450 the brake lights seem to be on a separate fuse #30 on the power distribution box in the front right side of of the engine.

That would be the first place I would look. If you have a 350, auto genius also had that fuse box. Just google it.

Could be a faulty brake pedal switch.

Not sure about the Windsport configuration for the tail lights. If both lights on each side perform the same functions then more than likely it is a switch problem. If, however, one light on each side is used for brake lights while the other is turn signals it could be a wiring issue.

Did the brake lights work during the PDI? If so it could be a loose wire or ground connection.

Don't waste your time going to a Ford dealer since they did not install the lights they will more than likely tell you it is a Thor issue unless the problem can be tracked back to the switch or Ford installed F53 light wiring harness.

After testing the fuses and tracing wires, we found a tiny switch behind the brake pedal that was tripped.

Glad you got it fixed; not sure I understand what you mean by the switch was tripped, unless it was a breaker, sounds more like maybe a defective brake light switch. Have had them come apart before where the thing was part way out its case.
