Fuse diagram for 91 chevy corsica

I DON'T KNOW. $1000 ASSEMBLIES ARE PROFIT MAKERS FOR DEALERS. I THINK ASSEMBLIES ARE JUST PLASTIC LIGHT SHADES AND NOT RELATED.
VISUALLY COMPARE PART NUMBER OR LOOK OF OLD BULBS WITH NEW BULBS. CHECK WITH CAR MANUAL.
WHAT IF THE LIGHT SWITCH OR RELAYS ARE FAULTY.?
AT NIGHT LOOK AT RUNNING LIGHTS. HAVE SOMEONE TURN ON LOW BEAMS.THEN HIGH BEAMS TO BE SURE.
YOU HAVE 3 LIGHT LEVELS. YOUR RUNNING LIGHTS AND HIGH BEAMS ARE WORKING BUT NOT YOUR LOW BEAMS. LOOK IN YOUR OWNERS MANUAL FOR THE HEAD LIGHT FUSES AND OR RELAYS TO SEE IF THERE ARE SEPARATE ONES FOR HIGH AND LOW BEAMS.

If this fuse box diagram below is correct you have a fuse for left low beam head light and another fuse for right low beam head light and a third fuse for both the high beam headlights. If the fuse is good for the right I think I would take the left low beam head light and put on the right side and see if it works on the right side. If you think you got the wiring correct. It may be the bulb is bad from the wires which shorted out. A voltmeter or test light to the socket would save some time switching the lights. I have had the socket bad before and had to change the bulb socket.

On the 1999 model, you have a relay for high and low beam circuits, and those relays send power thru a fuse for each side. The relays and fuses are in the fuse box in the engine compartment.
Check your owners manual for details.

Fuse #7, a 10A fuse, is for the left low beam headlamp.
Fuse #8, a 10A fuse, is for the right low beam headlamp.
Fuse #23, a 15A fuse, is for the high beam headlamp.

Well the high and low beam lamps use the same fuses, and the dimmer switch handles the ground circuit. So I would check the dimmer switch if both high beam bulbs are ok.

Sounds like the high beams blowed on one and the low beams blowed on the other you just need a new set.

You didn't mention the year and model but if you have the owner's manual it will have a fuse box diagram and tell you if a separate fuse is used for the low beams. Normally though one fuse takes care of all head lights. You may have a bad dimmer switch that will need to be replaced. Please rate this answer, thanks.

Good Evening, a blue light on your dash has been an indicator that the bright lights are on. There is nothing wrong, just simply turn them off and use your low beam lamps by moving the dimmer( turn signal) switch.

a lot of newer cars have seperate fuses for both left and right head lights both high and low beam. you should check your owners manual to see fuse locations and designations for your head lights.

Check the fuses under the hood...chances are it's one of them....there's not much left to check after that....check the fuses inside the car as well...it might be the high beam switch is bad that switches the low beams to high beams inside the car.
