2. Clean the battery terminal and post using a wire brush to remove corrosion.
3. Reconnect the terminal and ensure it is tight.

3. Test and Replace the Starter Relay

Sub-steps:
1. Locate the starter relay in the fuse box (consult the owner's manual for exact location).
2. Remove the relay using a screwdriver if necessary.
3. Swap it with a similar relay (e.g., horn relay) to test functionality.
4. If the clicking sound persists, replace the relay with a new one.

4. Inspect and Replace the Starter Motor
