Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, Phillips screwdriver.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Remove the Glove Box

Open the glove box and remove any contents.
Locate and remove the screws securing the glove box.
Disconnect the dampening arm and gently pull the glove box out, exposing the HVAC components.

3. Replace the Cabin Temperature Sensor

Locate the cabin temperature sensor (typically near the blower motor).
Disconnect the sensor's electrical connector.
Remove the sensor from its mounting location.
Install the new cabin temperature sensor, ensuring it is properly seated.
Reconnect the electrical connector to the new sensor.

4. Reassemble the Glove Box

Reinstall the glove box in the reverse order of removal.
Ensure all screws are tightened securely and the dampening arm is reattached.

5. Clear Error Codes
