i have a 98 blazer and read in the manual that you have to use the dome override button for this
Dome override button has nothing to do with headlights,but with the interior lights in your vehicle. So it depends on what your problem is exactly.
I would start with the fuse, the bulbs and then the switch...in that order. If it ends up being bulbs, see sources and related links below.
It is probably the running lights that are working and the regular headlights aren't working because of the switch or wiring. TAke it to a garage.
Use your high-beam headlights at night whenever it is legal and safe.
turn on your headlights
Headlights need to be used at night, when it is dark, and when windshield wipers need to be used.
You would not drive it at night or when the law says you must display headlights.
