I have a 1991 Buick Century 3.3L 3300 v6 engine 184,000 miles. The steering column seems like it's very loose and sometimes the car shifts from drive to netural on it's own also when you put the turn signal on the ignition switch turns off. I hope it don't need a whole new steering column. I'm going to take it in and pay the $90 diagnostic charge and see what they come up with but if I can get some advice I would appreciate it. Thank you.
