You gotta realize that the switch ain't where you put the key! The switch is located on the top of the steering column well under the dash. Replacement is not too difficult, I will post the %26quot;book%26quot; instructions. There may be other problems with the actuator or linkage to the switch. It may also have become out of adjustment. Check the adjustment per the following instructions. This type of Ford switch is known to %26quot;loosen up%26quot; meaning where te switch slide is held in by bent over tabs, over time it will become loose. New switch should cost under $20.00, Good Luck!

Not the easiest thing in the world to do. Tedious unscrewing all those little screws and removing the trim pieces to get to the switch.1989 Thunderbird?
Just pull the trim panels off from around it.You have to have the key in the switch.You'll see a hole in the aluminum with a steel pin up in it.Use a small punch or nail to push the steel pin farther in and pull the switch out.
