    My interior lights stopped coming on when I open the doors. They still work via the switch, but I can't figure out what or why they are no longer coming on when I open the doors or unlock the truck.

    I haven't changed anything recently. I did have a fuse blow a month ago that controls the accessory plugs in the cabin. Swapped the fuse and all was well.
    Until last night.
    Makes me think I have an electrical issue somewhere.
    Any ideas?

    Did you accidentally bump the switch to the left of steering wheel?

    Check your settings on your head unit.

    I was going to ask the same thing...I don't touch that switch often...got my truck back from the dealer in daylight...later that evening, got in my truck in the garage and noticed no interior lights and no headlights after I started it up...forgot to check switches...techs always turn off the interior and auto-headlights when its in the shop...set switches again...problem solved with good laugh...

    If your interior lights don't come on at all regardless of switch position, I would say the interior light fuse. When I replaced the halogen bulbs with LED, I shorted out one of the map lights and had to replace the interior fuse (under the hood). But if it just doesn't work when in the middle position...

    Checked head unit, didn't see anything related, but will check again.
    The lights all work, just don't come on when I open a door or unlock the truck.
    I need to look for the switch to the left of the steering wheel. I don't remember hitting it though. The one I am thinking of is only for the cargo light, not the interior lights.

    Here is the panel that Ron is referring to...switch in top row, middle that says "Door" middle position turns on "Dome" or ceiling lights when door is opened (Thanks Ron!). This is the one that techs usually turn off when she's in the shop and sometimes I hit it when cleaning. bottom left switch that looks like a cargo truck is for Cargo and Bed lights (if you have bed lights connected).

    The part in the head unit settings that is related is where you set the reaction to lock and unlock using the key fob...horn and lights, horn and no lights, lights and no horn, etc. and the how long the lights are on.

    Switch.
    Obviously bumped it with my knee getting in or out yesterday, and didn't have time last night to ferret it out properly.
    Thanks everyone.

    Guys! My dome light switch is coming detached from the dash, so before I crack into the dash and try to fix it, I'd like to have a new switch in hand...but I cannot for the life of me find one online to order - any ideas??
