2. Disconnect the Hoses
Identify the two hoses connected to the heater core. Use pliers to loosen the hose clamps and disconnect the hoses. Cap the hoses to prevent coolant leakage.

Remove the trim panel below the steering wheel and unscrew the screws holding the instrument cluster in place. Carefully pull the cluster out and disconnect the electrical connectors.
