Thank Chryco Psycho.. I ended up replacing the switch. Everything is now working like it should. I think part of the problem was the yellow wire from the light close to the ignition switch was crushed against the steering column and looked burnt.. So I took care of that also.
Had the problem last November, no turn signals or left rear brake light. So I replaced the turn signal switch. Last weekend took the challenger for a spin. Now no rear brake lights. Have new brake switch that is good and has power. I pulled the steering wheel, the turn signal arm was lose so...
