How to replace ignition switch? I have an issue with my 99 TA where once in a while you go to start the car and the security light turns on and the car wont start. You wait until the light goes out, about 5 min. and it will start. For a while I thought it was the starter relay, as when this would happen, I would carry a spare relay, put it in and the car would start. But the relay was taken apart last time this happened, and it was fine. I had a mechanic hook up a meter and when this happened, the readings comming from the ignition was all over the place. Tested the key resistor, and it read fine. I guess the little wires inside the ignition switch are frayed or worn inside. So how do you replace it? Also what saftey measures to take with the air bag since you have to mess around with that area?
This seems to be a common issue lately. I've had it happen a few times and am debating on how I want to do the fix. Not sure if I want to tear into it or just do the resistor fix.
Either way, this is not my info and was taken from a kind local (CatSkynr) who posted it on a local F-body board.
Hope it helps:
