How do I get to the fuse for the headlights?
Headlamp fuse on 2004 Chevrolet Impala
The circuit for the headlights are protected by fuses in the Underhood Fuse Block. The Headlamp Relay is located in the Driver's Side Instrument Panel Fuse Block. I am pretty sure you'll find more details in the owner's manual. You can get the owner's manual for you vehicle here; http://repairpal.com/automobile-owners-manuals-online
