Check fuse for low beam and daytime running lights, if good check bulbs and make sure the filiments are good, some systems require both lights to work, meaning if one is burned out they both might not work..

SOURCE: 2007 buick allure headlights will not turn

As you described the problem the solution is to replace the headlight bulbs, they have two elements one for normal lighting or low beam and one for high beams. the elements for the low beams are continuously used and are subject to burn sooner.

2002 Dodge Caravan headlamps: one works on dim the other works on high beam but not together. Also only one daytime running lamp.


Your van has dual diligent headlamp bulbs, that means each headlight has one bulb that serves as high beam and low beam. What has most likely happened is on one side the low beam filament has burnt out, and on the other side the high beam filiment has burnt out. The daytime running lights are just the high beam filament running on reduced power, so if the high beam doesn't work on one side, that same side will have no daytime running light. Replace both headlamp bulbs with matching, good quality bulbs.

Only hi beams work ...no low beams . Lamps and fuses are good. Replaced relay, no change. Keep reading about ground wire from lights can not find it


The wiring schematic changes drasticly depending on whether your vehicle is equipped with daytime running lamps or not. However, both systems have one thing in common...the low beams and the high beams get their grounds from the same place. If the high beams are working correctly, the ground is not your problem. The most common causes of low beams not working and high beams working are the multifunction switch (or as Toyota calls it: "Combination Switch") and if your vehicle has daytime running lamps, the Daytime Running Lamp Module could be the problem.

Sounds like you need a bulb,the daytime running lights send power to the high beam wire so they look like low beam lights are on but really they are high beam lights running on low voltage.
