Re: 1992 Crown Vic, ignition switch not unlocking
For part of the last year, the key was not really required to turn the ignition switch, but it would not go all the way counter clockwise to locked steering position. Thus the car was vulnerable to stealing once a person was able to enter the car. Also the keys left in ignition bell sound was constant when the door was open, even though the keys where not in, the steering was not locked. I replaced the Commutateur Interruptor Switch last year, which had a lifetime warranty, so I thought it was the part that failed. I removed it yesterday and traded it for a new one under warranty. While I was replacing this, I realized the key was getting very hard to slide into the ignition switch, and finally would not go in at all. Therefore, while I had everything apart, I removed the ignition switch and purchased a replacement, with keys, from AutoZone.
When I went to re-install, I realized the sliding linkage rod, that has the Commutateur Interruptor Switch pin hole, will not slide back to the furthest rear position (towards driver), therefore not allowing the steering and switch to go into the locked position and allow for key removal.
