No lowbeam headlights

High beam switch moat likely, have you checked relays and fuses?

You'll probably have to remove something, i.e. Grill, battery, radiator resivior,etc.

open hood and look down inside front you will see wires going to the front lights you will need to turn the plastic lock ring counterclockwise then when that is done gently pull out the bulb and socket take out old bulb and put in new one dont touch the new one with hands use cloth to put in oils from hands make the bulbs burn out faster also there should be two bulbs in your vehicle one high beam one low look to see if outside is low by turning on headlights before changing bulb

First check, is there more than one headlight bulb, if so, the low beam bulb has failed, needs replacing.

If not you'll probably find that the head light bulb has a double filament, low and high beam. The low beam filament has failed. You have to replace the bulb.

how are the headlight bulbs..i have seen many mechanics change all kinds of parts and turned out to be just both lamps coincidently went out at same time

i had same p w 1996 gmc chgd bulb chgd switch checked wires in steering coloumfinmally went under dash where your left boot would be and wiggled a 3quarter by half inch relay and done it lite up all day of jackin 2sec fix

the filament on the low beam burnt out. but the high beam didn't. You have a filament for each. 1 for high beam and 1 for low beam in the same light bulb. You need a new head light.

check the wire connection for your lowbeams

Could be a bad ground, defective bulb sockets, or defective multifunction switch.

try replacing the fuse because low beam and high beam are two different systems
