3. If the voltage is low, consider replacing the alternator.

3. Check and Replace Fuses

Tools Required: Fuse puller or pliers
Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
2. Identify the fuse for dashboard lights using the fuse diagram.
3. Remove the fuse and check for continuity; replace it if blown.

4. Inspect Wiring and Connectors

Tools Required: Screwdriver set, wire brush
Sub-steps:
1. Visually inspect wiring harnesses leading to the dashboard for any signs of wear or damage.
2. Clean any corroded terminals with a wire brush.
3. Ensure all connectors are securely fastened, and repair any damaged wiring as necessary.
