caused a weak fuse to burst.
Check your fuses.
Change the head-light bulb.
charging a battery will not keep a headlight or any other light from working.
Headlight blown?
Loose wire?
Bad ground on headlight?
Check all the obvious first
Changing the terminals won't have any effect on any lighting, but it may make some things like your radio lose their settings.
Your headlight probably has one of its two elements blown, and you'll need a new headlamp (unless the Hummer has separate globes in each headlight, which I doubt).
I recently just changed my battery terminals and 2 days later my driver side headlight won't turn on.... But all the other lights work just fine. Do you think changing the batter terminal had something to do with ?? The car is a 06 hummer h3
Sorry this is a repost but I just found out my when I turn on my high beams the light works just fine
