Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery using a socket wrench.

2. Disconnect Battery

Locate the battery in the engine compartment.
Use a socket wrench to remove the negative terminal clamp.
Ensure the terminal does not touch the battery post while disconnected.

3. Wait and Reconnect

Allow the vehicle to sit for at least 10 minutes to discharge residual power.
Reattach the negative terminal clamp securely and tighten it with the socket wrench.

4. Check Climate Control Module

Start the vehicle and allow it to idle.
Test the climate control functions (temperature adjustments, fan speed, etc.) to check if the module has reset successfully.

5. Inspect Fuses (if necessary)

If the problem persists, locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse associated with the climate control system and inspect it for damage.
Replace with a new fuse of the same amperage if the old fuse is blown.
