I have a 2005 Crossfire Limited. Is anyone had an issue with the interior dome light staying on when the switch is in automatic.

 

My 2005 roadster has the same problem with the interior light. I noticed my trunk light is missing. I don't know if this has anything to do with the problem.

 

The dome light and cargo light are common to fuse 9 in the under hood accessory block.
In automatic mode, the ground to cause them to light is supplied by the BCM ( Body Control Module ) on pin 18 of connector 4.
The BCM is reading all the door and lift gate / trunk switches ( via the CLP - Central Locking Pump ) in order to determine if the lights should be on or off, so I would suspect one of those 3 would be the culprit.

 

Are you sure that the trunk hatch is closed properly?
Slam it and check the bulb again.
This has been the solution for some people here.

 

I wonder why it is that I try to over-complicate things, and you get right to the heart of the issue ?
BTW, the switch for the trunk latch is built into the catch mechanism ......
