Thread: blinker problem

Tweet

I've got a 67 mustangstock 289 3 speed. The right rear blinker, and the left front blinker doesn't work. It's not the bulbs I changed the rear ones and it didn't help. The hazards, headlights, tail lights, brake lights, and other two blinkers work. Any help would be appreciated cuz I suck at wiring. Thanks!

I had the same kind of problem when I build my vette. It ended up being in the turn signal mechanism inside the steering column.

If you don't have one, go out and pickup one of the 12 volt test lights. They sell them everywhere, from 5 bucks on up. They look like an ice pick with a wire test lead coming out of the top, with an alligator clip on the end. The idea is, you clip the alligator clip to a good, known ground, and when you touch the point to a wire, the bulb inside lights up, letting you know there is current there.

The ice pick end is so you can stab into the insulation of a wire into the copper core, and test wires that way. To get a Known good ground, I like to run a jumper wire from the negative post of the battery to give me some extra length, then there is no question about having a good ground.

This tester will allow you to start probing inside the light socket and then working your way back until you find where you lost current. Being that one light is out on one side and the other is out on the other side, I think you just have a corrosion, bad contact situation somewhere.

Can't trouble shoot it entirely for you via computer, but start at one light, and see where you are losing current, or possibly you have a bad ground on those lights.

Good luck,

Yup, check it the way Don suggest, Mustangs are notorious for bad lamp sockets an bad grounds. Do the bulbs look good, or did you actually try a bulb you know works in the socket? Sometimes the element can be broken in the socket where you can't see a break in it.....

Ya my 53 did this. after hours of checking every wire and socket i found that it was in the steering column.

If the brake light works, its not the wires to the back end, the signal light is the brake light. Sounds like a steering column problem, the signal switch is no good.
