Low Beams Don't Work

[Darth Plasma]

I took my 87 K10 out for a drive last night and guess what. Pulled the dimmer switch and only the parking lights come on. No low beams. But the high beams work fine (I do have a burnt out headlight, and they're all pretty weak so i gotta replace them anyways) So i had to drive around on high beams, but they're not very strong so it didn't really cause any harm. Anyone know why the low beams won't work? I'm thinking its a ground issue or maybe a fuse since the parking lights work. Or maybe you gotta twist the dimmer switch knob for them to come on and I'm just dumb enough to not realize that. Help is appreciated. Thanks!

Are you sure the other low beam didn't burn out?

Check the bulbs first, then check the grounds. My guess is you will find a bad or corroded ground, especially since you said the high beams are dim.

I’m gonna go check the ground. My dad pointed out that my ground connections looked pretty bad so I’m gonna go check that out
