If it is like the one on the Old's cutlass and all the other GM's, if you
pull the panel from the underside of the dash below the steering wheel you
should be able to see it the switch on the left side of the colum (a lot
easier then pulling the wheel) it will have a rod coming down from the
steering wheel that goes into it, check and make sure that it has not come
loose from the colum. if you do have to it is part of the ignition switch
so you have to replace both of them and I think the last one I did a few
months ago cost about $80.00 from NAPA
