My shifter broke do I have to replace the whole steering column

ok my shifter on my steering column in my 98 chevy regency broke its completely loose and dangling and seems like its completely un attached it moves freely up and down but doesn't engage in the gears do I need to replace my entire steering column also my turn signals won't engage when I turn them on left or right but both signal indicators on the dash light up solid and stay lit up when I apply the breaks what is wrong ive replaced fuses fuse relay and still nothing
