ignition switch
 

hey guys,
Ihave a 98 expedition eddie bauer that doesnt turn off when the key is pulled out.
The engine shuts off but none of the accessories do (radio, lights, subwoofers), when you open the door the alarm goes to tell you the key is still in the ignition. whats the best way to fix this as i am consistantly waking up in the morning toa big blue paperweight.
cheers guys, Alistair
