Headlight problem: My headlights don't work unless I turn on high beams?

Power flows from fuse 32 (15A) in the fuse block under the left side of the dash, to the headlight switch. From the switch, it flows to the low beams on a light blue wire. Check the fuse. If it's good, check for battery voltage at the headlight switch. If you have power there but not at the headlight bulbs, you have a break in the wire somewhere

i would prefer a year make model engine size :-)

i've seen both low beams go bad. one, then the other later down the road. i've seen dimmer switches go bad. swap relays and check fuse. it'd be a good first start. use a test lamp at the headlamp connector (without damaging the terminal!) and follow the schematics from there.

Check out the low beam fuse but the low beams can fail simultaneously but that is rare.

Check the headlight low beam fuse. Change it if it's bad.

If every car were wired exactly the same way, answering your question would be easy.

But you've made the wrong assumption. Every year, make, model is wired differently.

Get the point?

No info = no answer.

Fuses, dimmer switch, wires, bulbs blown or the wrong ones!
