    66 brake/turn signal light not working

    The right side stop/turn signal light is not working

    Both (left and right) tail lights work
    Left side brake/turn signal element works

    I've disconneted the rear harness under the dash and tested the right side wiring to the rear, it's good. What I did was clip the two right side wires (tail light and brake/turn signal wires) then tested continuity at the block under the dash. So I'm certain the wires are good. It isn't the bulb or housing as I also tested with a volt meter and the brake/turn signal wire is not getting any power.

    I just got the car, so the only manual I have so far is the AIM. Looking at the wiring section of the AIM it looks like the brake light switch wiring goes through the turn signal switch. I have not checked continuity from the under dash block to the turn signal switch yet, but if it is good, what are the odds that my turn signal switch is bad?

    Any other troubleshooting suggestions before I spend $50 for a new switch?

    Thanks,

    Don

      Don, it sounds like you have the problem, the directional switch is a common problem. sometimes you can wiggle the switch and you'll see the directional indicator light.Make sure to look at the connector under dash, The terminals can sometimes back out.

          Don, do you have telescopic steering on that car? I had the exact same problem with my 65 telescopic column. I put a new signal switch with wiring harness in and it works great now.

              No, mine is not the telescoping column. My problem ended up being a pin backed out of the harness connector. Looks like when a former owner put in a signal switch he didn't get all the pins seated in the connector. Turn signal/brake light working great now
