I have a 2004 FX4 f150 with 230+ thousand miles. My brake lights have stopped working. The tail/running/parking lights illuminate, along with the 3rd brake light. Only rear brake indicators/ signals do not work. Changed brake pedal switch and all fuses are good...Really mind boggling!

New bulbs?

AlexMotley

Bulbs are good, they've been replaced...multimeter confirmed is not the bulbs. Multimeter also confirms no power is being sent to the bulbs when pedal is engaged.

Sounds like the wrong bulbs...running lights work but no brake ?

I've changed the bulbs... There is no power even being sent when brake pedal is engaged. There's a disconnect somewhere.

Are you checking at the switch or the socket? Might need to start and one end and work towards the other with your meter.

Did you happen to hook up a trailer or brake controller to your truck? It sounds as if you blew the fuses. They are located in the small fuse panel behind the passenger kick panel.
