My ignition switch has been telling me it needs to be swapped out for about a year. Key was difficult to get into the ignition and difficult to remove with a little jiggling. Well, today I was driving home from the office and I cranked the motor and felt and heard a "snap!" in the ignition switch and knew it was kaput!
This was confirmed when the AC unit lit up (normally) but no air blew out of the vents. Common problem when the ignition switch has failed... some or all of the accessories go haywire.
Anyway...
So I get home and turn off the motor and the key cannot be removed. I am able to stop the motor though. But I hear this faint humming sound coming from the passenger side engine compartment fan. So I remove the terminal on the negative side of the battery thinking something's still getting power to it and this is not good.
Something in the engine compartment is still making a quiet little humming sound.
Any thoughts as to what it might be with no electrical power going to the car?
