Solution

1. Software Update

Go to the settings menu on the central display.

Wait for the system to reboot and test the climate control buttons again.

3. Inspect Climate Control Fuse

Open the driver’s side door and locate the fuse panel.
Remove the fuse cover and identify the HVAC fuse (refer to the owner's manual for the exact location).
Use a multimeter to test the fuse for continuity. If it's blown, replace it with a fuse of the same amperage.

4. Check Wiring and Connections

Remove the climate control module (if accessible) by unscrewing the fasteners and gently pulling it away from the dashboard.
Visually inspect all wiring and connectors for damage, corrosion, or loose connections.
Reconnect any loose connectors and replace damaged wiring as necessary.

5. Replacing the Climate Control Module (if necessary)

If the above steps do not resolve the issue, the climate control module may need to be replaced.
Disconnect the battery to ensure safety before replacing the module.
Unscrew the module from its housing, disconnect the wiring harness, and replace it with a new module.
Reconnect the battery and test the new module for functionality.
