Q: Electronics not working right

asked by on

The car horn randomly goes off, and the windshield wipers activate. The ignition is not working. I can temporarily clear the condition by disconnecting the battery.

There may be a fault in the electrical system where these items share common circuitry. A loose or corroded connection can wreak havoc across multiple electrical circuits. Have a mechanic experienced in automotive electrical systems inspect the wiring for faults. Consider one of our experts here at YourMechanic.
