Fuses are all good, and blinker box is good. Any help will be greatly appreciated.

Hi,

My primary concern is fuse 1 in the cabin fuse box. If you already checked that fuse, I need you to also check for power to it. The fuse could be good, but not getting power.

Here is a link you may find helpful:

I attached the wiring schematic below for the circuit. I had to cut the pic in half to make it readable for you. I highlighted the areas of concern.

Pic 3 shows the fuses to check. Make sure there is power to and from there. If there is, then we need to check the wiring to the multi-function switch and brake light switch.

Let me know.

Joe

See pics below.

Hi,

By chance, did you also check fuse 5? It should have power with the key in the run position.

Let me know.

Hi,

If the fuses are good and have power to and from, then we need to check for power at the brake light switch and multi-function switch. At the switches, locate the purple with an orange tracer and the white with a red tracer wires, and check for power.

If you refer to the schematic above, you'll see which ones I'm referring to.

Take care and let me know what you find. Note, we are tracing the wiring at this point to see where power is lost.
