Here goes, 67 camaro convertible. Pull the light switch out so parking lights work and left blinker indicator light comes on on dash and remains lit. Left brake light works but right doesn't yet all parking lights work and the left front signal lights works if I move the lever up and down to simulate blinking but no others work. If I pull the light switch all the way out the left turn signal light on the dash that's lit in park goes out and the front parking lights go out and the left front blinker will not work even when I simulate blink. I've tried changing/swapping the rear bulbs w/o any luck. Any ideas or suggestions would be appreciated.
