Headlights, both high beam don't work

Check the headlight connector terminals for power and ground with a meter or testlight. If there's a problem with either circuit, trace the wiring to the groundpoint and check for for power at the correct switch terminals before replacing it. It could well be the switch, but I like to know what's actually wrong before I throw expensive parts into a car.

I had this same problem with my 01 Honda Civic 1.7L,. Went Dealer (Factory Defect) and fix this problem. After Market Headlight connection was bad.

Had the same issue with my girlfriends son 2001 honda civic. they worked & stopped working. Tested all the fuses & relays..& took out the headlight switch & foundout, one of the pins on the wiring got burnt/hot & basically stop making a connection. Apparently this is somewhat a common thing. So, I replaced the new switch and it works like new!! It didn't take long to put the new one in. Three screws on the column & Two scres holding the switch in place. Took 15 minutes if that. Always look at your wiring. Nothing lasts forever... lol
