On my wife's 2003 blazer, she has had an occasional problem with the ignition not going into lock position so she can get the key out. It will start and kill the truck just fine, just doesn't turn all the way back to the lock position. The one time that it happened while I was around, I wiggled the gearshift and the key and ignition switch turned all the way back. I'm 99% sure it is a problem with the mechanism that keeps it in park with the steering wheel locked until the key is turned on.
My question, what does that look like? Will I find it by removing the airbag? removing the steering wheel? Is it lower on the steering column? Is it mechanical or an electric solenoid? I understand what it does, I just don't have a clue how it works.
I have the Haynes manual on this vehicle, it talks about a "ignition lock cylinder control actuator' which leads me to believe it may be a solenoid actuator that would or could be dependent on the park/neutral switch.
Any help would be appreciated. Just need someone to point me in the right direction.
