Ok, i have no brake lights.

Fuses, bulbs, relays and stoplight switch are all in working order....what else do i need to check?

 

Do you have turn signals and emergency flashers?
Maybe thr grounds?

 

flashers and turn signals both work, all my lights work except brake lights

this is a 2004 f150 btw

 

Does the CHMSL work, or is it all 3 brake lamps that do not work ?

2004 SCab, is this the New body style, or the Heritage ( like the 99-03 ) ?

 

all three brake lights are out

It's the new body style super cab

 

Might want to go back and check the fuse and the BPP ( Brake Pedal Position ) switch.
Not sure what relays you posted about with the stop lamp circuit, there are no relays in the circuit to be in working order.

How did you test the BPP ?

 

It did end up being the switch on the brake pedal

Thanks for the help guys
