Interior stay on while driving. Will go out 15 minutes after exiting vehicle. Have checked stock switch, doors all closed, hatch and back glass closed, delay lights off. How to fix???

 

More likely than not, the black wire in the drivers door boot broke. You need to pull back the black boot between the door and frame and re-solder it. The BCM is designed to turn them off after 15 minutes. Could be other wires but check the black one first. There are plenty of videos detailing this repair on line. I'd suggest seeking them out.

 

Yeah, the BCM isn't getting a signal that all the doors and hatch are latched. This usually sets off a chime and a VIC message, but not always. You don't, by any chance, have the dimmer all the way up, do you? That will keep the lights on as long as the ignition is on, then will time out via the BCM when you park it after 15 minutes. The last 2 positions of the dimmer switch control the brightness of the odometer, clock, and VIC for daytime lights-on driving, and the last position turns on all the interior lights for rummaging around inside while driving.
