Problem:
None of the interior lights or cargo light will come on when the door is opened. They do not come on with the roller on the switch either. The reading lights will turn in if I reach up and click them though.
It isn't the door lock/ajar sensor, since when the doors are opened, i will get the ajar notice on the overhead and the chime.

I have tried:
Checked all connections.
Replaced headlight switch
Checked the bulbs.

This is on my '08 2500 Laramie

 

Have you checked your fuses? Sometimes a burnt out fuse can make things act stupid...

 

Sorry, I forgot to add that. I had also gone through and actually replaced every fuse.
