1st you will need two tools, you can get them from any auto parts store like NAPA. See picture at end of the GM steering lock ring depresser, a must have.. INSTRUCTIONS: Remove steering wheel. Underneath is the turn signal switch. There is a ring around the steering shaft holding the steering wheel lock plate down. Push down on the lock plate and remove the ring and the lock plate. Next is the turn signal switch. 3 screws holding it down one on the right side above the key and 2 on the left. Probably have to move the turn signal switch left and right to get them. the arm is held on with one screw. Remove the hazard button, one screw in the end of it. There should be enough slack in the turn signal wires to get it over the steering shaft. On the top side at the bottom of the ignition switch there should be a screw. Remove screw and the ignition switch will just pull out. Reverse to install.
Hello, Dan. First, disconnect the negative (-)/ground on the battery Dan are you
mechanically inclined. If not then don't attempted this job.
need to remove all the plastic covers on the steering column. Remove the horn
ring.--two screws under the steering wheel. Remove the horn ring and disconnect
the horn plug. Remove the steering wheel nut. Use a steering wheel puller to
remove the steering wheel.
Remove the turn signal switch that fit around
the upper part of the steering column. Then remove the some of the parts that

Now, look at the
ignition switch flange, it a big chunk of aluminum. Now look for a large
aluminum dowel pin 5/8" in diameter that is driven into the chuck of aluminum
but it is parallel to the steering column.
This aluminum dowel pin will
have to be drill out before you can get ignition housing off, If there is
adjustable steering column lever, remove this also.
Now, once the dowel
pin has been removed, looking for a **** in the ignition housing. Take chisel
and insert into this ****, drive the chisel into the **** until the ignition
housing is loose to be remove by sliding it up over the steering
If you buy a new ignition switch, on purchase the switch with
keys. Don't buy the hole new ignition housing.. If you do it will get
In the ignition (old) housing drive out the ignition switch
pins that keeps the ignition switch in the housing. Install the new ignition
switch re-insert the ignition switch hold pins.
I am fairly sure that
Carquest/ NAPA some other larger auto parts will have ignition housing bolt. If
they try to sell you a replacement aluminum dowel pin don't buy it. It is almost
impossible to install the aluminum dowel pin without the proper tools, so use a
bolt to squeeze ignition housing together.
Before putting everything
back together. Now, check the new ignition switch to make sure it works. I wish
you lot of luck. GB...stewbison
The switch on Your Jimmy is mounted atop the steering column assembly, hiding under the dashboard. You must lower the column to reach it. If you have the replacement ignition switch with You or want to remove it first to make sure you are buying the correct one, follow these steps to remove and install it.
Set the ignition key to the off position.
Detach the negative battery cable using a wrench.
Remove the steering wheel column lower trim panel using a Phillips screwdriver.
Detach the steering column from the under dashboard frame using a wrench or ratchet and socket. Support the steering column to keep it from falling.

Unfasten the two ignition-switch mounting bolts using a wrench or ratchet and socket.
Slide the ignition switch off the actuating rod and remove it from the steering column. Installing the Switch
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.
Slide the new ignition switch into the actuating rod, making sure not to push the slider inside the switch.
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 wrench or ratchet and socket.
Remove the pin (if the new switch came equipped with it) from the switch slider by hand or with pair of needle-nosed pliers.
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.
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.
Install the steering wheel column lower trim panel using the Phillips screwdriver.
Attach the negative battery cable using the wrench.
if you want to change ign switch it is bolted to the steering column if you want to replace the key lock cyl you need to remove steering wheel and turn signal switch but you need special tools to do that
The ignition switch(this is the electrical portion) is out of time. It needs to be removed, reindexed(notched teeth on top of switch-rotated a couple spots) and reinstalled. When it is installed correctly, the tell tale lights will not be on, you'll have accessory and the vehicle will start in the crank position. You don't want any lights on when the key is out of the ignition.
you have to remove the steering wheel, turn signal/emergency flasher switch assembly and a couple other pieces below that. If you have tilt steering the little clip is easy to remove but hell to get back in so if you are not the patient type take a break and try installing it again a little later.The ignition switch should be held in by a bolt. Once the bolt is removed the ingition switch slides out and the new one can be installed.
