Your high beams work but your low beams do not because the switch is broken that switches between high and low beams. Electrical switches wear out.
The switch assembly is probably worn out and malfunctioning.
Should be like any other vehicle. (pull turn signal stick back (high beams on), pull it back again (high beams off).
Bad bulbs Bad dimmer switch
As a guess both low beams are burnt out The daytime running and high beams are the same light filament. Or the fuse or the relay for the low beams.
are my low beams supposed be come on also when my high beams are on in my 1994 gmc sierra
check the bulb low bean burns out before high beams
None
pull or push the turn signal lever.
Bad dimmer switch.
Headlights have two filaments; one for low beams and one for high beams. There is a good chance that the low beams are burnt out. This doesn't necessarily mean that the high beams won't work. However, it's not too common for both low beams to burn out at the same time. Of course, it could be a fluke. I would replace the headlights with new ones and then go from there.
just because. how is a rainbow made, why is the grass green we don't know it just is
it could be your dimmer switch is getting bad
