STUMPED! Brake light wiring question

I am wiring the lights on 2012 bed I just put on. I tested them all and they worked, so I started putting shrink connectors on. I get them on, and the drivers side brake light doesnt work. Turn signal works, running light works, reverse lights work.....everything works except the drivers brake light, and it shares a wire with the turn signal...which works...? I checked my fuse diagram and nothing says the brake lights are independent, but that's all I can think of.....am I missing something?

Does the E-Flasher cause both to flash?

This is beginning to sound like a multi-function switch in the steering column.

That's what I was thinking.

John,

Do you have a wiring diagram for the Exterior Lamps Circuit, especially the part about the multi-function switch (MFS)?

You're looking for a LT GRN/ORN on Pin 9 of the MFS connector that goes out to that lamp in the rear.

Never mind, they started working.....I started checking all the fuses and they were all fine, and they worked the next time I tried...

It's possible that the MFS was somewhere in mid-throw. That would cause what you saw.
