Make sure you disable the air bag system prior to any work on the air duct by isolating the negative
Battery Cable and ensure you wait at least two minutes after unplugging the negative battery cable, so the capacitor is completely discharged and the accidental air bag can't deploy. Don't damage the front area of the panel while performing this work. Start with removing the instrument panel from the car and placing it on a bench, after that, take off both interior air outlets, the two outer ducts and the top pad. Then, open the demister ducts and remove the three screws connecting the defroster duct to the instrument panel main cover. In the end, move the defroster duct ahead so it comes off the instrument panel top cover and remove the duct.
