Classic/Antique Car Repair: 1967 Camaro dash light problem, 1967 camaro, dash light

Question
Our 1967 Camaro's driver side turn signal works fine on the outside of the vehicle, but when you have the dash lights on, it does not work, but the passenger side light will come on.  What could be wrong?

Hi - I think you mean that the indoor light will not blink. is this correct ? well I would check the front and rear bulbs, and the grounds , you can clean them with sand paper. or the flasher for the blinkers might be blown out.  if you turn it on when the right side works it will makes a clicking sound , that little box is what you might need.
