So I was replacing my third brake light on my first gen taco. Plug in the new one, doesn’t work. Plug in the old one, doesn’t work. Tried multiple times. And all other brake lights work. Suggestions?? Thanks in advance.

Short or fuse somewhere. I have the same problem with one of the tail lights on my Jetta. Replaced the bulbs, replaced the module, replaced the fuses. Sometimes it wants to work, sometimes it doesnt.

where would there be a short tho? Literally was just working. And couldn’t find any forums on fuse. From what I’ve read the third lights have a built in fuse.

Also was being really careful unplugging. Just one connection which is plug and play. If that helps.

Deff not by the light. I tried to follow it but i would have to remove headliner to see exactly. Can’t find a wiring diagram.

I spliced them, and still nothing.

It’s only one 10amp fuse that controls all those lights. All other brake lights work. Deff not the fuse.

That headliner is no fun to remove. I have done it in a extra can and a double cab. A,B,C pillars have to come out and the seats to have room to maneuver it around and it's still sketchy. If I remember right the wire for that break light is on the driver side rear pillar. Try to see if there is power at the fuse box then at the pillar. Electrical Gremlins suck.

I’m in for a mission now. Will probably do this tomorrow since it’s pitch black out and chilly.

but regarding your statement, looked like it was going down center. Does it curve to driver side?

On a side note, I just did the gray wire mod and everything worked (idk about the 3rd light). Would that affect it? Everything is grounded properly tho. Or else the locker wouldn’t turn on without the ground.
