My daughter's 92 Z24 has what I suspect is a bad ignition lock assembly. You have to hold the key in the on position to keep the car running or the key will turn back to the off position. My question is, how do you replace the assembly? Do I have to take the steering wheel off, or can I take the cover off the steering column? Also, are there any tricks or potential issues to be aware of? I looked through the forums and didn't see this answered anywhere. I've done key and tumbler assembly's on other cars but they basically popped right out. Any help is appreciated.

I just talked to someone who said they think the problem is the ignition switch rather than the ignition lock assembly. Thoughts?

Wow. Not one reply? Well, for anyone else facing a similar problem it was the ignition switch and not the ignition lock/key assembly. The repair manual basically tells you to remove the steering wheel and the remove the steering column from the car. Don't follow the manual.

You do not need to completely remove the steering wheel. First you do need to remove the panel that contains your horn (you will have to disconnect it as well). Then remove the 6 torx head screws from the steering wheel. Remember the position your steering wheel was in so you do not mess up your alignment in the process.

After that, you will remove the top and bottom panels behind the steering wheel. There should be 3 torx screws holding the bottom panel in. Remove those. You will also need to remove the handle on the left hand side of the steering wheel that adjusts the height of the steering wheel. It screws off. There will be two torx screws, one on either side of the steering wheel that connect the top and bottom panels together. Remove those. The panels should come apart fairly easily after this. Remove both of the panels. The ignition switch will be on the bottom left side of where the steering wheel was. It is held in by two screws and have two sets of wires coming out of it. Remove the screws first as this will allow you to remove the wires easier. Remove the two sets of wires.

After this, take your new ignition switch and reverse the process: put the wires back in, put the screws back in and secure it in place (Before you put everything back together, temporarily reconnect your battery to make sure everything works. Disconnect your battery after the test and start reassembling.), replace both of the panels and screw in the two screws that hold the two panels together, put the three screws under the bottom panel back in place, put the steering wheel back on in the same position that you took it off and screw it back in place, reconnect your horn and put the panel for the horn back in place, and screw the handle to adjust your steering wheel height back into place. Reconnect your battery. After that, you should be good to go.
