Hi beams work, low beams dont

2000 Nissan Quest.

high beams work, but the regular low beams dont.

same bulbs for both. bulbs are good.

fuses are good

You might check for the voltage at the socket for the headlight bulbs. There should be power between one prong of the socket and the ground post on high beams. Switch to low beams and seeif you have power from the other prong to the ground prong. If you don’t, the problem could be a relay or the dimmer switch. If you do have power, the bulbs both have the low beam filament burned out. Since low beams are probably used more than the high beams, it is likely that both low beam filaments are out.

Good chance it’s the headlight switch . On some cars it’s a five minute replacement .
