Hi, to me this doesn't sound like a column issue, sounds more like a bad ground in one of the lights, or modules in the back light clusters. when power is applied to one bulb, and there is no ground for that bulb, electricity can backflow through another grounded bulb and illuminate it. i think you should check this first, but if you want to get in the steering column, first disconnect the battery power, then ground, and leave disconnected for at least two minutes before removing airbag. the airbag has screws from the backside of the steering wheel to remove, usually only two, one on each side, but sometimes four. when you remove the screws, they may not come all the way out, meaning, loosen them until they are loose, they might stay there. then pull straight towards you to remove airbag. there will be a yellow connector and a horn connector to remove, and if you have cruise control in the steering wheel, there will be two small connectors for this to remove. when you go to remove the steering wheel, make sure you mark the clocked position with a marker pen before you remove so as not to re-install incorrectly. also make sure to have the steering wheel centered and straight with the front wheels pointing straight ahead. when you press off the steering wheel, there will be a plastic piece called a clockspring that you pulled the connectors out of. note exactly which way the connections is and make sure to either tape it to this placement, or don't move it around when removing. if you turn the clockspring one turn, one way or the other, when you put back on, it will be overclocked one direction and when you go to make a turn the other way, it will break internally causing the air bag light to come on and you will get to replace the clockspring. one more thing, place the airbag facing upwards when storing during repairs in case it accidently goes off, it will not lauch into the air like this, and store on an open area.
