[Jeffry72]

On my 67, I have tail lights, I have brake lights, and I have turn signals that all work. When I turn on the right turn signal and step on the brakes, it works as it should. But when I turn on the left turn signal and step on the brakes, the right brake light won't come on. I'm more familiar with 70-72's, but is there something peculiar about the 67's?

My guess would be turn signal switch

2nd the TSS... Retest while wiggling, pulling, pushing on the turnsignal lever.

Best guess is the contact in the TSS is arc'd or lost it's "spring" and isn't making contact for the RH side in the signal mode.
