Unhappy Right front turn signal

I have had problems in the past with turn signals but am stumped with this one. The right front turn signal does not work. Neither will the hazard signals work for the right front. The housings are new and well grounded. They worked until I had to take the gauge cluster out for a speedo problem. Not getting any voltage at all to the housing. Does anyone have any ideas? The last time I had problems was with the main connection into the cluster but it is in solid and I have no other problems.

Thanks in advance.

Re: Right front turn signal

Check the connector at the steering column going to the turn signal switch. It might not be plugged in all the way. The right front turn wire is dark blue. Check this wire with a test light. If it flashes there, then check the same dark blue wire at the fire wall bulk head connector.

Re: Right front turn signal

Have you checked for a severed wire around the cluster/dash?

I find that if I carefully trace the harness from end to end, putting eyes on every inch of the wiring and every single connector/connection, I often find the culprit without any electrical testing at all in the case of no power conditions.

Finding electrical gremlins is a special kind of torture, so I feel your frustration.

Re: Right front turn signal

You can isolate the problem with a 12v jumper wire hooked to the blue wire on the body side of the connector at the steering column. If it lights the lamp, then the issue is in the turn signal switch. If not then you need to trace the wire forward to see where the voltage is lost.

You're just jealous because you can't hear the voices!

Re: Right front turn signal

If you can, post what vehicle you are working with.

This can be real important as some may look at this thread and without a year, make and model, it's just too general of a question and may not get answered or get you on the path to getting the issue resolved.

Another question I have is, does the instrument panel's right turn signal light come on with the flashers activated or when the right turn signal is turned on ?.

While the below is for a 69 Nova, the basic setup is the same for a 69 Chevelle BUT we don't know if that is what you are having issues with.

Re: Right front turn signal

I sent a 12v signal thru the connector to both L&R turn signals. The right one was dead, so as you suggest I will look downstream. I find it hard to believe it is the bulkhead connector since it was recently apart and cleaned so I'll start under the hood.

Thanks again,

It wouldn't be that bad if it wasn't so cold.

Sorry, I thought that I had posted the vehicle but it is a 70 Chevelle SS 454

Yes, next place would be the bulkhead connector. Especially if it was apart.

Re: Right front turn signal

I finally solved the problem. Sent a 12v signal thru the bulkhead connector to the dark blue right turn signal wire and it still didn't work. Removed the battery and found the factory connector to the lamp had the dark blue GM spade connector had released from the connector and wasn't supplying power. All the way to the end of the circuit.

Thanks, Everyone

Just to expand on things, is in your situation the front turn signal light did not work due to the connection issue by the battery. The indash right turn signal light should have been working as this part of the circuit was before your issue.

Glad you got things figured out.
