After having the problem with alarm going off and not allowing the engine to turn over, now I have a different problem. Got the battery charged, checked out at Auto Zone, reinstalled got a different alarm code. Got that to clear, now the car will start, but will not shut off, continues to run with key in "off" position. Dealer said to disconnect battery, no joy car still ran. Reconnected battery, pulled fuel pump fuse still runs. Pulled the diode in front fuse box, it shut off. Four relays in trunk still energized, any help will be appreciated.


Thanks, Dan

 

Never disconnect the battery like that! Can damage all sorts of things - bad bad dealer.

Probably your ignition switch is not actually going off internally. Or there's a relay - possibly engine run relay - sticking on.

 

OK JagV8, is there anything I can safely lube the ignition cylinder with?. When I got home I reinstalled the diode, car started, cylinder felt funny, when key was installed there was no resistance from the off position through the accessory area. when I tried to shut it off, I jiggled it a few times, then there was some pressure and it now will shut off. Don't want to replace the switch if I don't have to. Is graphite safe?, I know it can cause electrical problems.


Thanks, Dan

 

Good advice from JagV8.

The electrical section of these switches is now starting to become an issue, and is age related.

Our Silver car had that "lack of resistance" from Off to 1, so I went digging, oh my, bad idea, but in too far to back out now. Eventually got the electrical bit OUT of the mechanical bit, probably easier if I had no arthritis, but a quick spray with contact cleaner, some Silicone Spray afte that, re-inserted, good as.

Spoke to a guy at work some days later, and the Ford Territory (Down here car) has a switch thet looks identical to the Jag switch, and they are having all sorts of failures of them, same complaint, car wont switch OFF, and a good clean/lube, and they are good to go.

 

Your car is 14 years old.


Replace the switch with a new one.

Yep, that was the plan for me at the time.

ONE problem, NO switches available in the colonies, situation NORMAL.

Now got 2 new switches on the shelf, and when I get that "warm and fuzzy" feeling again, I will delve in there and swap them both out, but dont hold your breath.

 

OK, sounds like sound advice. I am new to these cars, is there a diagram anywhere that will show me how to remove it?.
Also, will anything need to be reprogrammed after I replace it?.

Thanks, Dan
