I have replaced the flasher relay twice. Still, I can only get the right turn signal to work, when I switch over to the left turn signal, I can still hear the flasher relay ticking but instead of illuminating the dash indicator or the turn signals on the exterior, it only dims the interior lighting.

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
