Solution

1. Preparation

Gather tools: OBD-II scanner (if applicable), flathead screwdriver, torque wrench, cabin air filter replacement (if necessary).
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter access panel under the glove compartment.
Remove any screws or clips securing the panel using the flathead screwdriver.
Carefully pull down the panel to access the cabin air filter.
Remove the old cabin air filter and inspect it for dirt or blockages.
Install the new cabin air filter, ensuring it is oriented correctly according to airflow direction.
Reattach the access panel securely.

3. Reset Climate Control System

With the vehicle in a safe location, open the climate control settings on the touchscreen.
Perform a soft reset of the climate control system by pressing and holding the brake pedal and the scroll wheels on the steering wheel until the screen resets.
Allow the system to reboot and check the functionality of the climate control.

4. Repair or Replace Faulty Components (if necessary)

If diagnostics indicate a faulty component (e.g., blower motor, temperature sensor), locate the component by referring to the service manual.
Disconnect the vehicle’s battery to ensure safety before proceeding with any electrical repairs.
Remove the faulty component according to service manual instructions and replace it with a new one.
Reconnect the battery and test the climate control system.
