Interior Lights Staying On

[Hurricane87]

As in, 24/7.  No switch turns them off.  Neither does the battery saver.

The only thing I've done electrically before this started was to tighten the positive terminal on the battery,  I know that didn't cause this.

Any ideas?

Perhaps your switch is broken and stuck in the on position. Not sure.

check fuses after 20 min the car shuts everything off if u leave lights on or radio or w.e it is.

Maybe disconnect the battery completely for an hour or so and see if the brain resets ...

(This is per the "classic" service manual, but may work on the 01-03?)

Put the MALL control module into diagnostic mode ...

- Turn the key on.
- Press and hold the power door unlock switch.
- Cycle the headlights on and off six times.
- Release the power door unlock switch.

If there's an actual fault in the interior lamp control circuits, you'll hear three bongs ...

To exit diagnostics, turn the key off.

Wouldn't be surprised to find out that's the infamous cracked wire in the door harness causing a short.

Disconnecting the battery changed nothing. I don't see the point in an elaborate diagnostic procedure; it isn't a switch, so it almost has to be electronic.

Does anyone know what the relevant module is called, and where it's located?

There is two plugs under the kick panel that you can try do unplug and plug it back in.

What's the kick panel?

The panel that under the steering wheel.
