Interior lights are on but no door alarm

[Robbabob]

Sometimes my lack of force shutting a rear passenger door will cause the Interior lights to stay on, but I do not get a door open idiot light. I'll be starting to drive out, then notice the lights on. Usually it's obvious and barely latched, but today it looked closed. I opened and closed it pretty hard, put the truck in gear and lights out.

Curious if anyone has seen this in their trucks. This is a low priority issue, but I'll look into any easy fix.

My TB does't have a door warning light, only light is for tailgate.

If u have the DIC it will show up which doors are open on it.. Also only light is for the tailgate as mentioned before.

hmmmmmm No DIC, so I guess there isn't an idiot light. oh wait, the interior lights are THE idiot light.

Thanks guys!

Alright... Stupid question, are the interior lights supposed to come on when the rear passenger doors open? Mine do not..

Means your door switches are not working, or a fuse, or a set of broken wires.

or......... the ignition switch needs replaced

Is there a separate fuse for just the rear?

There are 'door ajar' switches in each door. The front ones feed into the DDM and PDM, the rear ones feed into the BCM directly. See bottom of this pic.
