You read that title correctly, the fuses are good, I replaced the multifunction switch, AND the brake switch. The running light comes on, blinkers work, and 3rd brake light works.

Any ideas? I am EXTREMELY frustrated.

 

This will sound like the stupidest question in the history of questions, but did you change the bulbs? I had both of mine go out simultaneously in my Aurora.

 

The bulbs were the first order of business, but thanks for taking time to respond.


The FIN tail light harness quick disconnect in the right quarter panel was loose!!!!


It was connected enough for the running light and blinkers to come on, but not the brake lights.


Put a fork in this Scooby Doo mystery, it's not always the Multi Function Switch.
