Brake Light

[ARK74J20]

1974 J20. I bought my 74 J20 about 1 year ago. I developed a new gremlin that I can’t figure out. My right rear brake light and blinker bulb doesn’t work. It lights up when the headlights are on but not the brakes or blinker. The left rear brake and blinker works fine. I have replaced the bulb: I have cleaned the bull socket. I have taken a wire wheel to the ground area and cleaned the connect and replace the ground bolt. Where should I look next? Help

Flasher relay would be the easiest thing to test.

If not there, it could be a bad contact in the turn signal switch.

Edit - since the left turn signal looks fine I would wager it's a bad contact in the turn signal switch since the brake light and turn signal are on the same circuit.

Thanks! That’s where I will start. Hopefully it’s the relay. I don’t want to tear the steering wheel apart

Have you taken a multimeter to the wire itself to see if power is getting to that blinker wire first of all ?
