Lighting issue

[Njones]

2014 chev suburban lt. Still has stock radio, no alterations.

 

1. Interior lights come on normally when you unlock doors or open doors

2. Interior lights come on if you rotate dimmer

3. Lights shut off if you hit the dome light over ride switch

 

4. If you turn on any dome lamp with their switch, the speedometer and radio lights turn off.

 

So 1-3 are normal behaviours, please help with 4
