Turn signals not working properly

Hi,

First, I attached the wiring schematic below for the exterior lighting and highlighted all wires related to the left signal lamps.

The first thing I need you to do is check the green wire with a yellow tracer for power out from either the front or rear lamp.

Here is a link you may find helpful:

Let me know what you find.

Since you hear the flasher ticking, we know power is making it to that point. So, it is being lost between the flasher and the lights. There is a splice in the wiring that may be the cause, but that is to be determined.

Take care,

Joe
