Door Switch Troubleshooting

Begin by locating the fuse box, which is typically positioned beneath the dashboard or in the engine compartment. Once you’ve found the fuse box, inspect the fuses to determine if any have blown or are damaged.

To test a fuse, a multimeter can be used to check for continuity. If a fuse is found to be defective, it should be replaced with a new one of the same amperage. It’s important to ensure the correct fuse is used to prevent electrical issues.
