Will not even do a flash indicator on the dashboard. Have tried to replace turn signal switch on steering column, flasher relay switch, and have checked the fuses. Nothing seems to be working and would really like to know what we can do to get these working again.

Hi,

First, make sure there is power to the fuses. Also, did you check or replace the signal / flasher relay?

I attached a couple pics below. The first shows the relay I am referring to. Pic 2 shows fuses you need to confirm are good and are getting power.

Next, I need to know if you checked or replaced the hazard switch. Power to the signals and the hazard lights go through that.

Pics 3 and 4 are the entire wiring schematic for these components. I had to overlap them to make them readable. I did overlap them so you can easily follow them.

Let me know what you find or if you have other questions.

Take care,
