Interior lights won't turn off

[Vdawg1115]

So today I noticed that the interior lights wouldn't turn off. Checked all the doors to make sure they were shut probably and everything seems fine. But while driving the lights stay on and they stay on even after I've parked and locked the doors. I am assuming it's the battery terminals? I've read from other posts that it could be the root of all little electrical quirks. I have disconnect the battery negative for now until I figure what it is. I guess I may as well upgrade the battery terminals just in case

It might be one of the door closed sensors. Small part, 2 min to swap out with a new one.

You sure you don't just have the interior lights turned on

lol. These are the lights when the doors are open. The other lights I can still click on and off. I will check again today when I get back

The interior lighting dimmer wheel on my H3 has a *very* small detent between full bright and always on position. I've accidentally bumped it too far up and the interior lights get stuck on even when all the doors are closed. Run the dimmer wheel down a little to make sure it's not just stuck on there. I've got to pull mine apart to see if I can mod it to make it harder to put in that position, or at least more obvious to me when it is being clicked in.

That's just the easy solution. Otherwise, I hope you have luck finding whatever switch is not working and still thinks a door is open or something. Actually, if you have a remote start system, isn't it possible that some relay is stuck, and the computer thinks the key is in all the time? That might keep the lights on.

While the battery terminals are crap and responsible for alot of headaches, I've never heard of them causing the interior lights to stay on. More likely to be a door switch (very common, don't forget the rear one, too) or the light switch detent like Burtor suggested.

When that happened to my wife's H3 a couple years ago, I had to disconnect the battery so it wouldn't drain. Turned out to be a bad BCM.

I don't know what it was. Seems to have self corrected itself. I did plug the battery back in. I undid and checked out the door sensors. Nothing seemed out of the ordinary

Oh man now I have this problem What should I do first?

Try the battery thing I did. If not, then maybe the sensors are indeed broken

you know what happened I have to confess. I ran my truck thru the car wash to get the the salt off her from the snow we had a
couple of days ago. So today I got into her she started she ran great until I stopped at a traffic light. Soon as The
light turned green and I started to drive the Chime comes on and my dash tells me the doors. I stopped opened and
closed all my doors and the 2 interior lights won't turn off. Mind you as I start to drive the warning chime comes on and my
2 interior lights turn off. But they turn back on when I stop. I had to unhook my battery in my garage so not to drain her.
But thank you so much I will do your procedure.

Does the H2 have programmable dash lights like the Denali? I am fortunate to have a friend who has a Suburban and could inform me of that 'issue'....

I have read many threads on electrical gremlins being blamed on the crappy battery terminals but I do not recall any about the interior lights. I would start by checking the wheel that adjust the brightness to see if it is clicking on and off. Then check all your door switches, which I think it is the culprit here. Here is a link to the part. Good luck.

Yes the culprit was the rear passenger door jamb. Less than 5 minutes to fix.
