Disconnect the battery's negative cable and isolate it to turn off the air bag system and after that, let the automobile sit for two minutes to let the air bag system capacitor release any stored energy. It's the only certain way to prevent the air bag system, since setting it wrong could lead to accidental activation and serious harm. The first step is to take off the negative
Battery Cable. After that, unclip the middle bezel and disconnect the connections from the back of the A/C-heater control on the instrument panel. Covering up the front of the center bezel can prevent damage while you work on it. Once you've secured the center bezel on a flat surface, remove the four screws from the A/C-heater control and take out the entire control next.
