1. Faulty ignition switch: The ignition switch is responsible for supplying power to various electrical components in the vehicle, including the headlights, wipers, and turn signals. A faulty ignition switch can cause these components to malfunction or behave erratically. Try turning the ignition key back and forth a few times to see if it makes a difference. If the problems persist, the ignition switch may need to be replaced.
2. Electrical Wiring Issues: Check for any loose or damaged wiring connections related to the headlights, wipers, and turn signals. Ensure that the wiring harness is properly connected and there are no exposed or frayed wires. Damaged wiring can cause electrical malfunctions and lead to the symptoms you described.
3. Faulty Headlight Switch: The headlight switch controls the operation of the headlights and wipers. A faulty headlight switch can cause the headlights to turn on unexpectedly and the wipers to turn off. Try turning the headlight switch on and off a few times to see if it resolves the issue. If not, the headlight switch may need to be replaced.
4. Turn Signal Switch: The turn signal switch controls the functioning of the turn signals. If the turn signals do not work or cause the vehicle to stall when activated, there could be an issue with the turn signal switch. Try operating the turn signal lever a few times to see if it makes a difference. If the problem persists, the turn signal switch may need to be replaced.
5. Stalling Issues: If the car stalls when using certain electrical components like the turn signals or headlights, it may indicate an underlying electrical problem or a faulty alternator. Have your vehicle's electrical system and charging system checked by a professional to identify and fix any issues.
It's crucial to have the vehicle inspected by a qualified mechanic or auto electrician to diagnose the exact cause of these problems and perform the necessary repairs.
