Solution

1. Preparation

Gather tools: Multimeter, socket set, screwdriver, and cleaning supplies.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery terminals using a socket.
Inspect the terminals for corrosion; if present, clean them with a wire brush and a baking soda solution.
Reattach the terminals securely, starting with the positive terminal.

3. Test and Replace the Battery (if necessary)

Use the multimeter to recheck the battery voltage after cleaning; if below 12.4 volts, charge or replace the battery.
If replacing, remove the old battery and install the new one, ensuring correct polarity.

4. Inspect and Replace Starter Relay (if necessary)

Locate the starter relay in the fuse box (refer to the owner's manual for location).
Swap it with a similar relay to test functionality.
If the clicking noise persists, replace the starter relay with a new unit.

5. Test and Replace the Starter Motor (if necessary)

If all previous steps are satisfactory, locate the starter motor.
Remove the electrical connections and mounting bolts using a socket set.
Install the new starter motor, tightening bolts to the manufacturer’s specified torque (usually around 15-20 ft-lbs).
