2006 Chevy Trailblazer: the fuses and relays..fuse box..lights work

This answer was rated:

I have a 2006 Chevy Trailblazer My low beam headlights do not work. I have checked the fuses and relays in the fuse box. All other lights work. Don't know what to check next.

Hello and thank you for using just answer.


The first thing to check is the HDM fuse in the underhood fuse panel. If this fuse is good, test for power on this fuse with a test light or voltmeter. If you have power on this fuse, turn the low beam headlights on and test for power at the LO HEADLAMP-LT and LO HEADLAMP-RT fuses. Let me know what you find.
