My cousin called me today because her GMC Blazer wasn't turning off. She was asking for me to take her battery out, but I knew the car wasn't going to stop if I did that because the alternator would still be kicking out juice, so I didn't bother doing all of those steps to cut the car off, she still had to drive home.
When the key was turned in the off position the dash lights, heater blow fan, etc would all turn off correctly. When the key was moved to the On position, all the dash lights, blower fan, etc started back up. So that made me rule out the ignition switch being faulty. But it has been 11 degrees and colder the past few days. I kinda figured it was due to the cold and something sticking somewhere.
My question is, what actually makes the car turn off when you move it to the off position? For example, on a lawnmower, the off switch simply grounds the spark plug wire to the chassis ground and short circuits it, so to speak. What exactly happens on a car?
