My square body suburban has a issue when the headights are turned on the dash won’t light up. I already replaced the headlight switch and still nothing. I disconnected the oem radio to see if that was a issue and still didn’t fix the problem either please help

 

Is there a separate dimmer wheel for the dash illumination, or is the headlight switch round and just turns to control dash illumination?

 

No it’s all in one

 

I got it figured out the marker lights went bad and when I replaced them the dash light came on but they are going bad as well so I’ll need to replace them too.
