Will a steering colume from a 1993 bonniville work in my 99 grand prix se

My guess. No. There are too many variables. I believe both used column and floor shifting. Those years cross the gap between Passlock systems. Find one out of the proper car and year. There are still 10 different options in that year, but you should be able to get an inexpensive one from a junk-yard. If it does have pass-lock the new cylinder and key will require programming or the vehicle will not start. What wrong with the column?
