i own a 2002 f-150 4x4, the airbag light just started flashing a sequence of two flashes then seven flashes, then after five or six sets of that  it stays on, also the key/switch & (orange light) for the pass/side on/off is no longer lit. any help with this problem would be greatly apreciated. thanks chad...
