Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the vehicle's battery to prevent any electrical issues during the reset.
Wait for at least 10 minutes to allow residual power to dissipate.

2. Reset the Climate Control System

Reconnect the vehicle's battery.
Turn the ignition to the "ON" position without starting the engine.
Press and hold both the "AUTO" and "OFF" buttons on the climate control panel simultaneously for about 10 seconds.
Release both buttons, and the climate control system should reset. You may notice the system recalibrating.

3. Final Checks

Start the engine and allow it to run for a few minutes.
Test all climate control functions including temperature settings, fan speed, and air conditioning operation.
If issues persist, consider further diagnostics or professional assistance.
