Reach under the dash and make sure the old switch is tight and the bolts have not come loose. The switch should not move.
Place the key in the off position.
Installing the Switch
•1. Make sure the new ignition switch is in the off position. Some aftermarket switches will have a pin on the switch slider, close to the base of the switch, to lock it in the off position to ensure proper installment. Verify whether your new switch has this pin.
•2. Slide the new ignition switch into the actuating rod, making sure not to push the slider inside the switch.
•3. Set the new ignition switch in place on top of the steering column, and start the two mounting bolts by hand. Then tighten the mounting bolts using the ratchet and socket. Do not over tighten the bolts. I believe it's like 35 inch pounds max.
•4. Remove the pin (if the new switch came equipped with it) from the switch slider by hand or with pair of needle-nosed pliers.
•5. Insert the key into the ignition lock cylinder; turn the key to make sure the rod is actuating the new ignition switch. Then turn the key back to the off position.
•6. Set the steering column in position against the dashboard frame, and start the mounting bolts by hand. Then tighten the mounting bolts using the wrench or ratchet and socket.
•7. Install the steering wheel column lower trim panel using a Phillips screwdriver.
•8. Attach the negative battery cable using the wrench.
•9. Start the engine to make sure the new ignition switch is operating properly.
