I have a 03 Chevy blazer my head lights went out when I turn my lights on my brights symbol come up but none of my front lights come on

 

Do the (inside bulbs) DRL's, (daytime running lights) work? Did you check the bulbs? Do the (outside bulbs) low beams work?

 

The inside lights work none of my lights work on the outside not even my drls

 

With the Key ON & headlamp switch ON, remove all 4 headlamp bulbs & check for battery voltage & ground at each headlamp socket. With the headlamp dimmer switch in the low beam position, check the outer sockets. With the headlamp dimmer switch in the high beam position, check the inner sockets. Use a test light or voltmeter. Post your results.

Check your fuses. If it is bad and you replace it and it blows after lights are turned on again, you may have a rodent removing coating off wires, causing them to arc together. Or maybe it ate right through light power wire all together. I've seen it happen once. Look for rodent nest up in corners uner hood.

 

I tried doing that but my head lamps won't come out of high beam but yet none of my high beam light work when it's on

 

When you click the dimmer switch, does the high beam headlamp symbol on the dash go on and off?

 

Maybe your ground wire from battery to body came off.

 

The high beam symbol is always on When I turn the high beam off
