Solution

1. Preparation

Gather necessary tools:
- OBD-II scanner
- Multimeter
- Basic hand tools (screwdriver set, socket set)
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Battery Voltage

Use a multimeter to measure the battery voltage.
- Reading should be between 12.4V and 12.7V for a fully charged battery.
If the battery voltage is low, charge or replace the battery as needed.

3. Inspect Climate Control Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the climate control system using the fuse diagram.
Remove the fuse and inspect it for any signs of damage or breakage.
Replace with the same amperage fuse if it is blown.

4. Disconnect and Reconnect Battery

Disconnect the negative terminal of the battery using a socket wrench.
- Safety Warning: Ensure the vehicle is off and all electrical components are shut down before proceeding.
Wait for at least 5 minutes to allow the system to reset.
Reconnect the negative terminal and tighten it securely.

5. Recheck Climate Control Operation

Start the vehicle and test the climate control settings.
Adjust temperature, fan speed, and check if the automatic climate control functions normally.
