Tools Required: Screwdriver set, trim removal tool.
Locate the cabin air filter access panel, typically found under the glove compartment.
Remove the screws or clips securing the panel and gently pull it off.
Take out the old cabin air filter, ensuring to note the orientation for the new filter.
Insert the new cabin air filter securely into place.
Reattach the access panel and secure it with screws or clips.

3. Reset Climate Control System

Reconnect the 12V battery.
Turn on the vehicle and access the climate control settings through the touchscreen.
Perform a soft reset by holding down both scroll wheels on the steering wheel until the screen resets.
After the reset, check if the climate control system operates normally.

4. Update Software

Tools Required: Internet connection.
Connect the vehicle to Wi-Fi.
Navigate to the Software section in the vehicle settings and check for available updates.
If an update is available, follow the prompts to install it.

5. Inspect HVAC Components

Tools Required: Multimeter, basic hand tools.
If the climate control still does not function, inspect the HVAC blower motor and resistors.
Use a multimeter to test for continuity and proper operation of the blower motor.
Replace any faulty components as needed.
