The power mirrors in my honda never worked and the passenger airbag goes on and off (with or without someone sitting on the seat). I took it to Honda and paid 99.00 they found spliced wires which were most likely related to market alarm system installation, the driver door multiplex was most likely damaged and or shorted. Further diagnosis was needed however, being a poor college student I had to opt out. $99.00 later and my car electrical system still continues to fail on a pretty persistent basis.
