Tail light problem
I've got a 1966 coupe. Sometimes my drivers side running light works. Sometimes my brake light and turn signal works. Sometimes both running light and brake and turn signal works. Most of the time, brake and turn signal work and no running light. No problem with passenger side at all. Any thoughts?

The only thing that ties the tail light to the stop light/ turn signal filament is the ground, so the guys are right. All the rear sockets, including backup lights, license plate light, and fuel gauge ground are tied together and feed through a black wire back up to the rear body connector under the dash and then ground to the inst cluster ground. Start with cleaning or changing the bulbs for that side to insure they are not corroded. Then check the black wire to make sure it connects to the light ***'y base beside it and to the main black wire going to the front. You may also have corrosion in the contacts in the socket, or where the metal base of the bulb should ground to the metal shroud of the socket
If it's not the ground, then you have two separate problems at the same time.

I removed my Rear Valance panel on my '67 to get access to the tail light wiring. Fixing my bad taillight ground without removing it would have been much more difficult if not impossible.
