There is two things that could be wrong .. check under the hood for your power distribution box .. its black and 3 inches wide and about 8 inches long .. this contains your relays. and some fuses. on the inside of the lid it tells which one is which.. look for low beam relay .. if it is ok check your low beam bulbs and make sure they arent burnt out.. these two things should fix your problem .. or at least one of these should .. holler if you need more.

there should be a fuse and/or relay that operates the low beams, or try replacing the bulbs.

IT may be as simple as replacing both head lights the high beam may be out in one and the low beam in the other, if not your proably looking at a faulty combination switch.

From the symptoms you describe it sounds as though your headlamp switch is dirty, broken or out of adjustment. I would disassemble it and find out what is going on.

SOURCE: 2005 Ford Focus ZX3 SES, the blue high beam

It sounds like you are confused about how your headlamp system is supposed to work. The DRL does not run on the High beam circuit, it runs on the low beam circuit. The fog lamps are supposed operate with the park lamps and also with the low beams, not the high beams. From your description, I would say that your system is operating as designed and you are having trouble telling High from Low. (Don't feel bad, that is why high beam indicators were invented in the first place.)

My 1984 chevrolet silverado high beams lights works and low beam lights, turning lights, emergency light and brakes lights don't work. I need help!

Those lights are on different circuits. The high and low beam lights are powered thru the headlight switch, the turn signals, brake, and hazards go thru the turn signal switch.
I would want to know if each circuit has power at the switch that controls it.

High beam headlights stuck on replaced switch same problem

It can be issue with headlight switch,but as its already been replaced.Try disconnecting high beam headlight wiring from headlight assembly and reconnect direct external wire from headlight switch to headlight assembly,then by switch see if headlight is getting off and turning on or not.

Low beam headlight drivers side don`t work. high beam it works.

Check tour bulbs first and replace if blown. If OK then check wiring backwards from light to dip switch.

Click headlights to low beam and no lights work on high beam

I'm not sure exactly what your problem is. When you "click" your lights to low beam, your high beams should not work. But if your low beams work when you "click" them on, but your high beams don't work when you "click" them on, you either have a blown fuse, bad relay or high beam elements burned out on both lamps. (Not so unusual) Possibly a bad "dimmer" stalk switch or bad wiring, too, but a little less likely.

High beams work low beams do not

you don`t say if you have checked the fuses for the headlights.if the fuses are okay and you know that the low beam filaments are working.you may have to feed power and ground directly to the proper headlight prongs from the battery to make sure the bulbs are good.then it could be a relay for the low beams or a switch for the headlights.you don`t say if you have daytime running lights on this car as there is a module for this system that may be the problem for the now low beams.

Low beam head lights not working - The low beams, both stopped working. The high beams work fine. I checked the fuses and all 4 are good. I even swapped the low and high beam fises just in case. No...

if the fuses are good then you need to check for power and ground at the headlight plug that attaches to the headlight bulb if you have a good power and ground there and the connections are good then the bulbs are both no good.or if you can tell the bulbs are burnt out by looking at them then you don`t have to check powers and grounds.you also can directly feed power and ground to the bulb and check both the terminals for high beam and low beam as you cannot tell which is which by looking at the terminals

Push the lever forward to turn on high beams, if they do not work when you do this. You need a new high/low beam switch.
