What new trick is my Jeep up to now?
When I turned off the engine the radio and HVAC stayed on. Yes, this is a feature in some vehicles.My Suburban does this. But my Suburban will also turn this feature off as soon as I open a door and thereby not run the battery down. Not so in my XJ.
Cycling the ignition switch did nothing to change the problem. Starting the vehicle and shutting it off a second time did resolve the problem. And the next time I turned the vehicle off things behaved as they should have. So this was a one time fluke. So far. However I now have to wonder when it will happen again.
And without the problem making itself evident I don't have anything to work with to chase down the root cause. My best guesses are the ignition switch itself going bad, or a relay sticking.
On a '96 XJ is the ignition switch attached to the base of the column like on a GM vehicle, or is it buried in that large bulbous box at the top of the steering column, just behind the steering wheel?
Any suggestions as to which relays would be the most likely culprit? Is there one particular relay which both radio and HVAC run through?
Intermittent problems are the most fun to diagnose.
