I have an 84 Camaro, auto transmission, and I was changing out the neutral safety switch on the shifter. Afterwards, the key won't move out of the accessory position, the ignition lock cylinder locked-up. I can pull the key in and out, but the switch wouldn't move at all. Also, I can now move the shifter thru all gear positions. Normally, it won't move out of park unless you have the key in the run position. I still have the shift console pulled apart. I noticed there's a rod that moves when you push the shifter button in, could that have anything to do with it? I tried putting in a new
ignition lock cylinder, same problem. Problem seems to be in the locking mechenism, none of the books I have cover it though. Any ideas?

This is going to be rough and not even from a camaro experiance. The tumbled ignition keyhole dodad that goes from ACC-OFF-ON-START possibly on your car runs a shaft that engages into an IGNITION SWITCH. Not the same thing as the tumblered thing-a-mabob. While the system was being worked on the shaft might of come out of the possible ignition swith. You might need a torques ended screw driver with the hole at the end for your ignition. The ignition switchs have gone to a toques with a point in them so that regular torques wont work. NAPA and others sell the special torques or whatever the star ended drivers are.
Oh yah. Hopefully all you have to do is reallign the switch with the shaft. I think the switchs are made of cheaper than cheap plastics so be carefull messing with the switch. One of my switchs went out one day so I found out the easy to remember way. Had to hot wire the car using electrical tape to hold the multi contact switch together and just push slightly forward to start. To turn the car off I'd just remove the tape hehehe. Cheaper than cheap plastic. It was the Lincoln LSC by the way.

greetings cz,

When you installed the new switch did you have the shifter in neutral and did you rig the new switch with a 3/32" drill bit inserted in the rig hole located at the top of the switch?
Just a thought and 2 cents worth!!!!!!!!!!!!!!!!!! [img]graemlins/beers.gif[/img]

i can help here i hope, im a locksmith and do alot of gm ignitions. check the linkage that operates the electronin switch which is on the lower end of the column it sounds like something is binding, the position of the shift selector shouldnt be a problem as you should still be able to turn the key in any position, it just wont start unless in the park position.

The problem turned out to be in the ignition switch itself. The transmission linkage on the switch had slipped and was in the wrong position. It blocked the rest of the ignition switch, wouldn't let it open beyond the locked position. When I removed the 2 small screws attaching the transmission linkage, it popped into the right position. I went ahead and replaced the switch anyway, too much work to leave the old switch in place. Thanks for all the input.
