Hello. I am having issues with a few of my roof marker lights not working on my 04 H2. I have replaced all of the lights with new bulbs but still did not fix the problem. I ordered new light covers with built in LED's and the problem still remains. The issue is in the front and back.

Any thoughts on what I could try next?

 

oceanbrave gave some info and a wiring diagram here https://www.hummerforums.com/forum/h...markers-42829/ maybe it can help

 

Thanks for the info.

 

I apologize for not being clear in my question the issue is in the roof marker lights.

 

yeah i know look at the PDF he posted. it shows the clearance lamps wiring
