I have checked fuses (all good). Replaced the relay plug and blinker switch and still nothing. Please let me know if you have advice for the next thing to check.

Hi,

I realize you checked the fuses. However, have you confirmed that there is power to the fuses? If you have and there is, next, check the logic module. See the attached pic for location. I circled the ground. If you haven't checked for power at the fuses, do that as well. Here is a link that you may find helpful:

Next, check to see if there is power to the pink and orange wires to the logic module under the dash. See attached pic.

Finally, if there is power to the logic module, you need to confirm power to the multi function switch (purple wire, orange wire, the brown wire, and the white wire). Note that you should check all fuses that are indicated in the schematic.

I attached a pic showing fuse location as well.

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

Joe
