Doug 57,
The left brake lamp is also the left turn signal lamp...or it's suppose to be. You are indicating that lamp won't light when the brakes are applied, but will light and flash when the turn signals indicate a left turn! You are SURE it's the same lamp!
It would seem to me that a circuit isn't being made to the left brake light ONLY when the turn signal switch is centered.
Could there be junk inside the switch, or a broken contact in the switch? I think if the turn signal functions on this side, it would exclude the flasher unit.
I searched for a typical turn signal wiring diagram, but alas, no luck. Maybe help is on the way!
