99-04 Mustang. Third Brake Light Works! Side brake lights don’t! HOW TO DIAGNOSE!

[@SAVAGE_Streams]

Can this be done on a 2014 mustang? I have only my 3rd light working and no turn signals in the rear

[@aheroictaxidriver3180]

Why not just bypass the multi-function switch?

[@JuanHernandez-mq2go]

Mine is the opposite. The 3rd inner light won't turn on, on both sides. Emergency, turn signal and brake all work. Looked at a wiring diagram and it doesn't match 100% the lightbthay won't turn on only had 2 wires instead of 3 like in the diagram. Any tips?

My first 15a is not getting power and I replaced it still no luck. What’s the fix do you think?

[@deadmangreedo]

I have running lights and turning signal but not brake light
