I drive a 97 Chevy Blazer, and the steering wheel will lock if the wheel is turned while the key is not in the ignition...it's an anti-theft feature. I'm not sure how it would respond if the key was in the ignition and the ignition switch failed...but obviously I'd want to stop the car!
So if I were in this situation: key in the ignition position, driving 50 mph, and the switch fails...what systems remain to stop the car?
- Will steering work, albeit stiff without the pump assistance?
- Will braking work...at all?
- Will shifting work (automatic, not manual)?
I'm sure the emergency brake will work...but at 50 mph I suspect it'll need some help. If down-shifting works, it might help slow the car.
So the question is, what should someone do in this situation (car is moving at speed, ignition switch fails)?
Edit: I realize this question isn't asking about a repair or maintenance...but I believe this is the best audience for this question.
