Yall I have a 2002 HD silverado neither dome lights or cargo lights work they used to but now they don't and when I press the button on the roof for the dome light my cargo light message pops up on the dash can anybody help me with getting these lights to work properly again also when you open the door the dome light does not come on but the message still pops up on dash for cargo light

Check the bulb(*).

May be a stupid question but which one i already changed the cargo light the whole assembly

Are the bulbs good in the dome?

Have you checked fuses?

Cargo Lamp and Underhood Lamp

The inadvertent power relay provides battery positive voltage to the cargo lamp and the underhood lamp. When the respective normally open switch is closed, the switch provides a ground circuit and the lamp illuminates. The cargo lamp is grounded at G203. The underhood lamp is grounded at G102.
