2 days ago i go to start my car and thew tumblers in my ignition switch were locked(I've never had this problem before), so I went out and spent $400 on a new ignition switch and the electric black box on the back. I got it installed and the ignition freely moves to accessories and the on position, but when you go to turn it over and get it to crank it just clicks.... but won't turn over. Please help before I have to take this into a GM dealership and get "rear ended" with prices. i'd love to just be able to either fix it on my own or atleast be able to let them know what I need done. Thanks in advance!!!!!!
