1. Check fuses: The first step is to check the fuses for the horn and wipers. The fuse box is usually located in the engine bay or the passenger compartment. Consult the owner's manual for the location and identification of the specific fuses.
2. Check wiring: Look for any loose, broken, or damaged wires that may be affecting the electrical connection to the horn and wipers. Pay attention to the wiring around the steering column for the horn and the wiring near the wiper motor.
3. Wiper Motor: If the horn is working but the wipers are not, the issue could be with the wiper motor itself. Check for any signs of wear, damage, or corrosion on the motor. Check the electrical connector to the motor as well.
4. Horn Relay: The horn is usually controlled by a relay. If the relay is faulty, it can cause intermittent or complete failure of the horn. Check the relay and replace it if necessary.
5. Check switches: The horn and wipers can be activated through switches. Make sure the switches are functioning properly. Try pressing and releasing the switches repeatedly to see if there is any response from the horn or wipers.
6. Electrical Connections: Check all the electrical connections related to the horn and wipers, including the ground connections. Ensure that all connectors are properly seated and not corroded.
If you are not familiar with electrical troubleshooting or do not have the necessary tools and skills, it is recommended to take your vehicle to a qualified mechanic or auto electrician for a proper diagnosis and repair.
