Courtesy Light Staying On
My door panel and rear hatch lights stay on with the doors and hatch closed and key out of the car. I have checked continuity on both door ajar switches. I have also pressed the coupe closed switch all the way down with a screwdriver. All lights still on.
I have to keep my negative cable disconnected when not driving or it drains the battery. Where do I look next? Any help appreciated.

Is the panel lights dimmer paddle all the way UP? If it is, this leaves the courtesy lights on at all times.
If the paddle switch is ok, the lights should turn off after 12-ish minutes. This is the Battery Saver feature in the CCM. If they do go off after the delay, check the door pin switches on the rear of each door for proper adjustment when the door is closed. Watch the DOOR AJAR light in the cluster with the key ON. This light is directly connected to each door switch.
Another possibility is that one of the outside door key slots is not "straight up". If the keyway is not aligned, the CCM thinks a door is being unlocked and turns on the courtesy lights.
