I recently just picked up a 64 Thunderbird, Tudor Hardtop. I have a small issue with the taillights... I'm sure it's not a terribly complicated issue... here's the symptoms:
If I turn the lights on, taillights work like normal. Left and right signals both work. Only the right brake light works. Only the right hazard light works. If the left turn signal is on, I don't have brake lights.
