After driving in a very rain recently, my front low beam headlight is out and my interior reading lamps will not go out until the ten minute timer has expired. Does anyone know where the fuse for the reading lamp (s) is located? I have looked through the owners manual fuse box diagrams and cannot find the fuse for them.

when you push the button for them (doors closed and engine running) do they not go out?...do they do anything???...check also the interior light wheel on the instrument panel to ensure it is not turned into the lights on part (the wheel for instrument panel brightness)...

I think the low beam not working may have been coincidental, but the reading lamps not turning off sounds like something got wet that shouldn't have.
I can't recall if the reading lights are on a shared fuse with other items or controlled by the BCM, but I would check the dimmer adjustment first as silversport suggests.

I felt like an idiot for driving around with my interior lights on, now I feel like a moron for not having checked the dimmer switch. New low beams this weekend. Thanks guys.

Whether an individual is brave enough or not to admit it, we have all done something of this nature before.
You're in good company.

So, how do I change the car I have listed?

I'm not sure about that 'good company' comment, lol. Some of us, well, never mind.

It's such a PITA to change headlamps, my advice is to change them all (high, low, DRLs) when you have the bumper peeled back. I presume that you have halogen bulbs?
