64 Brake Lights - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Our son picked up a 64 C20 and the brake lights are not working. Spent some time yesterday tracing everything and trying to minimize what the issues could be.

Turn signals work with or without the headlights on. Tail lights work with the headlights on. There was some previous wiring splicing happening in the rear, but power is coming to the rear connection plug OK. Validated that the brake switch is working.

The headlight switch is sensitive, pull it out to far and the headlights will turn off. So we ordered a new switch. Could that have anything to do with it?

I'm assuming then it comes down to the turn signal switch since that is where power goes for distribution after the brake switch. Any other suggestions?
