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.
