My 1999 F150 left brake light doesn't work, can anyone help?

Asked by Mar 08, 2017 at 09:30 PM about the 1999 Ford F-150 XLT Extended Cab Stepside SB

Question type: Maintenance & Repair

My 1999 F150 left rear brake light doesn't work. ALL other lights work;
front/rear turns-parking-hazards-reverse-license plate-head light-fogs....
Literally every other light works, except my left brake. I've replaced the bulb,
socket, pigtail, multifunction switch and checked all the fuses and have a
good ground. (Checked by connecting to the body and thru a known ground
wire running a bulb that was burning at the time.) When I jump a wire from the
right brake to the left, it lights up when applying the brake pedal. BUT the
LEFT turn signal activates when I engage the RIGHT turn signal. Remember,
the left turn works fine while wired normally and when the jump wire is
installed to the right brake. I'm at a total loss. The only thing I can think of is
the brake light switch on the brake pedal??? But does it supply power to
BOTH lights thru a common wire, or are they wired separately? I'm
exhausted. Anyone have any ideas on how to fix this?

Thanks,

Dan H.

I don't have a wiring diagram for that model but here goes, you have running lights for night time one wire that splices in the back to feed two , brake lights run through the directional switch and when you turn on the signal it cancels the brake ,each has it's own wire . Worn sockets , grounding , rotted connections , weird stuff happens.
