Why your wipers and interior lights not working and the central locking system?

If your wipers, interior lights, and central locking system are not working, it could be due to a blown fuse, a faulty relay, or a dead battery. A blown fuse can interrupt the power supply to these components, while a faulty relay may prevent them from functioning properly. Additionally, if the battery is weak or dead, it can affect multiple electrical systems in the vehicle. It's advisable to check the fuses first and then inspect the battery and electrical connections.
