Brake Lights Inop!?!

[MPTonyT]

I have a buddy with a 2003 6.0L with brake light issues. Basically this all happened at once. Not sure of the cause. Both brake lights on the back of the bed do not work, turn signals do and the light between the cargo lights works. I swapped every relay under the dash and checked all fuses. no luck. Anyone have a wiring diagram so i can track his issue down?

This also takes out his trailer brake lights as well. Any input or things to check would be great. Email to send schematic to if anyone has it is mptonyt@gmail.com

Thanks,
Tony T.

Well if u have checked ur fuses, look by the brake pedal you should should see the brake pedal pressure switch, make sure you have power going to the switch and coming out of it when the pedal is depressed. i will try to get u a diagram later.

My wife called her father (who is a master tech) and he said... "oh thats easy... its a Ford right... cycle the emergency flashers a few times. that'll fix it" sure enough... Brake lights work again
