Key turns to the point where it should be trying

My key turns to the point where it should be trying to start the car with no resistance. Its like its missing the mechanism inside the steering column

I just replaced the ignition lock in my 1970 Torino and took it for a test drive. I shut the car off and gassed up, when I went to start the car back up my key went from accessory all the way forward without and sort of resistance at all. My wipers and heater and turn signals were not working on the test drive, which I found odd. When I was messing around with the key trying to get it to work the heater would randomly come on along with the turn signal.

i think I need a new ignition switch but I really wanted some expertise in the area. Thank you for your time
