The horn has stopped working. I have changed the fuse. That is not it. Can you tell me where the horn is located under the hood. And the high beam light and the dash is on with the service wrench light. I have replaced the high and low beam bulbs but the head lights on the left(drivers side) still does not work. Pls help

Hi lisasean,

Horn is located next to front impact bar.

Right and left headlights has different fuse but works by the same control in combination switch.

Check for battery voltage at headlight Dark Blue wire. If voltage is not present, either fuse is blown, wire harness connector is bad or you have a broken wire from fuse to bulb.

The service light showing means an error has been detected and you would need to get a scan done to find out the Diagnostic Trouble Code.

We took the car to the dealership for the light and horn problem and they found on the main wiring harness from the lamp harness to the firewall 2 broken wires at the multipack connector under the air intake box. Hope this helps someone else out there because it cost us $400. At the dealership to have it repaired.
