Hey guys,

First time poster here after lurking around here for years.

Have an unusual problem that I need some kind of direction on...

My only functioning indicator light is my driver's side rear turn signal/brake light. The other three are not coming on. They will not come on with the hazards or turn signals and the passenger's side brake light will not come on either. However when the headlights are on all of the lights will light up as running lights.

In response to the problem I have changed all of the bulbs and also the flasher unit under dash with no results.

Thanks again for the years of answers and hopefully more in the future.

It sounds like you could have multiple issues - so that will make things harder to diagnose. Did you put in an electronic flasher? That might help localize the problems.
