Here is a written procedure for R&R of Grand Prix Ignition Switch and Harness Assembly that works. A lot of us have used it. Good luck!


BEFORE BEGINING THIS REPAIR REMOVE THE NEGATIVE TERMINAL FROM THE BATTERY. IT IS NOT POSSIBLE TO DO THE REPAIR WITHOUT DOING THIS.

Look inside the slot where the tilt steering knob is located. There is a black metal piece where the knob inserts into the tilt mechanism. Pry it back slightly with a small screwdriver. One from an electronics tool set will work. While you have it pried, pull the knob out and it should release.

Remove the two screws from the bottom of the steering column cover and remove the cover.

Remove the two screws that hold the top steering column cover in place.

Insert the ignition key into the key cylinder and turn the key clockwise to the start position. Nothing will happen because you have disconnected the battery prior to starting this project. Lift the top steering column cover being careful not to break it because it is still held in place by the ignition key cylinder. You will see with your mirror near the back end of the cylinder housing a small hole. Stick a small allen wrench in the hole, this will release the key cylinder so that it can be pulled out. Once the key cylinder is removed the column top cover is free to be removed.

The black box below the key cylinder with all of the wires coming out of it is the ignition switch that you are changing. Look at the switch you have purchased for this repair. Notice that the small white plug with two wires attached has a tab on the side that can be pushed down, this is the release for the plug-in. Using your mirror you will see that plug-in against the ignition switch housing where it plugs in. Using a small screw driver press the release tab in against the plug and rotate the plug 90 degrees to the right to remove it. To do otherwise may break the plug.

Remove the plug from the white key release device by inserting a small screw driver and pressing the release tab on it.

Undo the two screws holding the ignition switch.

Undo the plug at the opposite end of the ignition switch by unscrewing the bolt in the center of the plug and unplugging it.

There is a black wiring plug on top and a gray one on the bottom of the ignition switch plug that need to be removed. This is done by prying the center of the plug case where it meets the ignition harness plug while sliding it forward.

Cut any tywraps holding the wire harness in place and feed it out of the dash.

To install do the reverse of the above, and tywrap the new harness into place. Be sure to properly align the key cylinder when replacing it in the housing and if the key will not come out of the cylinder there is a silver key release button at the bottom of the white device in front of the ignition switch. Press it and the key will come out. Also when replacing the ignition switch make sure that the slot in the switch is properly aligned with the corresponding part on the steering column that fits in the slot.

So you have to put your key in the old igntion to do this< it seems hard> but i can work with this< do you know about how much the part cost.

And also, will this peice fix the problem with my Key getting stuck in the ignition< B/cuz i've been having to push the button under the sterring wheel to get the key out and also< Do you know all tools i need for this job and the sizes< if you dont know> Do worry about it i find out the hard way< But thanks anyway.

Ball park figure is around $100. The ignition switch can cause BTSI problems too which is not being able to remove the key because the shift interlock solenoid is missing 12 volts.

Not hard but a little tedious. Just follow it to the "T" from start to finish.

A lot of us have used ths procedure and it works.

Is this a dealership part or can i just get it at auto zone< what about the Transponder thing in the key< does that have anything to do with the ignition< do they have to match up to read each other to start<

The part is GM/Dealer or AC Delco authorized seller only. AZ will not have it. The key tumbler is separate and doesn't have to be replaced when you do the ignition switch and harness assembly therefore you should not have any Passkey problems after replacement.

This is the part:
