Both headlights went out on 98 Chevy S10. Fuses are good. Fuses under hood also are good. What could the problem be? Voltage regulator?

You need a good auto electric repair shop, this is just to complicated to fix over a keyboard, sorry.

You may want to have alternator tested possible the voltage regulator failed and its overcharging.

Check circuit breaker and switch at dimmer end.

Try checking both a; your fuses, and b; check your bulbs. You should have two fuse boxes, one under hood and one in or under the dash. Check those for bad, blown or weak fuses. And check your headlights bulbs for them being good and their connection. If this doesn't fix your problem, you may check out your highbeam switch.

Not a regular fuse for headlights. Usually a relay that trips if it overheats and resets when it cools off. Often under the hood. Probably means you have a short circuit somewhere. A hot wire touching ground , often at rear of vehicle, Are your tailights still on ? If headlights and taillights go off together then problem is definately a short.

Check headlight fuses and relays.Two locations possible.End of dash on Dr.side and relays maybe under the hood to thr rear of batterie on Dr.side.

WELL YOUR 12 VOLTS TO THE PARK LIGHTS ON EXTERIOR OF CAR COME FROM THE HEADLIGHT SWITCH.. ALSO THAT VOLTAGE FEEDS THE INSTRUMENT CLUSTER... KEEP IN MIND THAT THE DASH DIMMER MIGHT ALSO BE BAD... WHEN YOU TURN ON PARK LIGHTS YOU SHOULD SEE THE DASH LIGHT FUSE GO HOT IF NOT SUSPECT THE HEAD LIGHT SWITCH

sould be under hood marked relays and breakers

Replace the Daytme Running Lamp Relay under the hood.
