Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the 12V battery negative terminal to ensure safety.

2. Inspect and Replace the 12V Battery

Sub-steps:
- Locate the 12V battery (usually in the front trunk).
- Use a multimeter to check the battery voltage; it should read around 12.6 volts when fully charged.
- If the voltage is low, remove the battery by disconnecting the negative (-) terminal first, then the positive (+) terminal.
- Replace with a new battery of the same specifications (typically a 12V AGM battery).
- Reconnect the positive (+) terminal first, followed by the negative (-) terminal.

3. Check and Replace Fuses

Sub-steps:
- Locate the fuse box (refer to the owner's manual for the exact location).
- Identify the fuses related to the malfunctioning systems.
- Use a fuse puller to remove any blown fuses (look for a broken filament).
- Replace with fuses of the same amperage.

4. Inspect Wiring Harnesses

Sub-steps:
- Visually inspect all wiring harnesses for fraying, corrosion, or loose connections.
- Repair any damaged wires by splicing and securing them with electrical tape or heat shrink tubing.

5. Reconnect Battery and Test

Sub-steps:
- Reconnect the 12V battery (positive terminal first).
- Start the vehicle and check if all electrical systems are functioning correctly.
- Monitor for any warning lights or abnormal behavior.
