ignition switch(96 mercury marquis) Sign In

Have 96 Grand Marquis, had to disconnect battery to turn car off. Replaced ignition switch. Now car won't turn on, and start lights (oil light, battery light, etc.) won't turn off when key is in off position. Can you tell me what the problem may be?

Did you replace the key cylinder, or the ignition switch down on steering column? If it is was the key cylinder that was replaced, look for a broken rod going to the ignition switch, or a mis-adjusted ignition switch on the column. If it was the column switch replaced, same diagnostics.

Thank you for your reply. After tinkering some more, I found what you are saying is true. I had replaced the key cylinder, not the ignition switch, which happens to be fine. It appears that it is the rod that the pin from the ignition switch goes into to turn car on/off, mounted on top of steering column. Was told this is a dealer part, but don't know what it would be called? Do you know if the steering wheel would need to come off in order to replace or can I just drop the steering column? Thank you for your reply in advance.

This would be a dealer part. You can go to any Ford dealer and they should be able to show you a nice diagram with part #s and you can just pick what you need from that. At least the Ford dealer near me does that for all Ford products.

Be carefull working on this. I don't trust the air bag and especially with a broken part around any wiring,

You will need to remove the steering wheel to replace the part. It is not a hard job, just a little time consuming. Just be careful of the air bag as Tom stated. It is best to disconnect the battery, then get a cup of coffee or a beer and drink it, then continue with repairs.
