Turn signals stop working

The right headlight and the front turn signals share ground G104. Therefore a weak ground will only allow one component to operate at a time, not both. Clean and tighten this ground to start with and we can go from there. Here is a wire diagram image, and a location image.

Hi,

I just saw we haven't been in touch with you for a couple of days. Has any progress been made?

If not, do the rear signals work and do they flash double time?

Let me know.

Hi,

That is an indication of an open circuit. The first thing I would check is the ground. You can try this.

When you get a chance, to determine if it is a ground issue, either check for continuity to ground via the black wire with a gray tracer on the left side and the black wire with a yellow tracer on the right side signal bulb socket.

Or, using a test light, place the wire on a known good ground location. The battery ground would be perfect if it can be reached. With the test light, check the blue wire with a green tracer on the left side and the yellow wire with a violet tracer on the right side for power. Do this with the lights on and the signals on. Have a helper turn the signals on for you and let you know if the flasher is double-timing.

I attached the entire wiring schematic below for the exterior lighting. I highlighted the wires relating to the signals.

Let me know what you find or if you have other questions. Also, note that the wiring schematics are two pages long. I had to cut each pic in half to make them readable for you. I did overlap them so you can follow from one to the next.

Take care and let me know what you find.
