I have a 94 Honda civic. My high beams don't work I was wondering why?

Okay so when I turn my headlights on, the low beams works. When I turn it the high beams on the headlight shut off and the parking light stay on.

Don't know Japanese cars, but my Ford's have a relay under the hood, one for the low beams & another one for the high beams.

Relay, fuse, switch. I don't have a wiring diagram.

Did you even pull a bulb yet to see if the element was broken?

If both high beam shut off then check the high beam fuse.
