2002 dome light switch?

2002 express
Having problems with dome/cargo lights.
Every vehicle I have ever owned has had a door switch to operate the dome light. Can't find switch!!!! Where is the switch so I can check to see if it is working properly?

Thanks for any Info.

Be sure to rotate dash light/dome light switch.
Door switch It is inside on the door latch.
Squirt some PB blaster on door latch and see if it shuts off.

If not you will need a body capable scanner to read out switches to see where the problem is.
