Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Remove the battery terminals using a socket set.
Clean any corrosion from the terminals and battery posts using a wire brush.
Reattach the terminals securely, starting with the positive terminal first.

3. Test and Replace the Battery

Use a multimeter to check the battery voltage. If it's below 12.4 volts, replace it.
Remove the old battery by loosening the hold-down clamp and disconnecting the terminals.
Install the new battery in reverse order and ensure it’s securely fastened.

4. Check and Replace the Alternator (if necessary)

Disconnect the negative battery terminal before working on the alternator.
Remove the serpentine belt from the alternator by releasing the tension using a wrench.
Unbolt the alternator from its mount and disconnect the electrical connectors.
Install the new alternator by reversing the removal steps and ensure the serpentine belt is correctly reattached.

5. Inspect and Replace Fuses

Locate the fuse box and identify any fuses associated with the dashboard lighting.
Remove and inspect the fuses; replace any that are blown with fuses of the same amperage.
