Everyone says it is the flasher relay, but it is not. I have tried four and none work. All fuses are good. What can it be?

Thanks for visiting 2CarPros.

The next thing to check is the switch. There are four wires. Three should have power and the black should be ground. To test the switch start by disconnecting it and using an ohm meter to check continuity to ground on the black wire. If it's good proceed, if not make a solid ground connection with that wire.

The next wires you will take and use a jumper wire or paper clip to connect to the black wire.

Dark blue to ground - hazards should come on

Light blue and white to ground - right turn

Light blue and yellow to ground - left turn.


I'll post the diagram below for you. Getting to the connector on the switch requires removing the lower and upper column cover. There should be three or four screws on the bottom cover and then they should separate once the screws are removed.
