High all, I have an '06 H2 with the factory light bar. Recently noticed the lights not working. Did some checking and found there is no power at the connector at the light bar. The switch inside still lights up. Checked the 30 amp fuse in the fuse block under the hood with a meter and it's good. I have been unable to locate another fuse or an actual wiring diagram so I was hoping someone out there might know where to look or have an idea where the problem may be.

Thanks, Rhett

 

check the power at the bulb sockets. the bulbs might just be blown.

 

Found another blown fuse under the dash so it's good.
Ordering a set of 4 LED replacement modules from Delta Lights in California, They can also refurbish light bars if you send it to them.

 

Got info on the replacements?

 

Hope this works, but here is the link to Delta Lights and the Hummer page.

Also for what its worth..... the optional roof and brush guard lights wiring kits includes 1 (or two if you happen to have both) relays that are strapped up above the parking brake pedal. That can also (rare but possible) cause issues. When you turn the switch on/off if you listen close you should be able to hear the relay.
