brake lites/right turn signal problem

Recommended Posts

1968 Tempest convertible.

Only the left turn signal and the left brake lights do not function.  Right side is normal.  Bulbs tested and swapped with no change.  Running lights and back-up lights are working.  Cleaned light fixtures and no change.  Bulbs do lock in place.  Checked connections at the brake pedal and in the trunk with no change.  Fuses are OK.  Any suggestions.  If I have to replace the entire left tail light fixture or maybe just the light bulb mating connector...how do I do that? Many thanks for any assistance.

A couple of thoughts come to mind. A broken wire or a bad ground. Have you visually inspected for any rusted or loose connections, broken wires - even under some of the old wire wrap? I would also inspect the bulb connectors themselves for rust or corrision. SInce the right side works, then that rules out the fuse.
