Head Lights My low beems won't work,the high beems work fine.The Bulbs are good,the realy is good the switch is good?????????????????????????

Could be dirty or burned dipswitch contacts. If the driver smokes this is not uncommon.

I suggest exposing the multiplug to the dipswitch and bridging the terminals as required to bypass the switch.

someone has switched the wiring harness sockets to the wrong bulbs or installed the bulbs in reverse. get in behind the headlight assembly on the driver side and reverse the wires, if that does not work then pull the bulbs and swap them inside to outside and vice versa.

the relay for your highbeem lights is bad, replace it and you should be good, or you could just switch the high beem relay, with the low beem relay, they are the same, and if the high beems work like that you know its full proof, if not... well you know, we will hafta move to something else.. hope you find this helpful

replace the bulbs.

check power wire which runs to the brakelight with a test light, get someone to apply the brake on and off and see if there is power getting back to that point, if no power check the switch on the brake pedal to see if power is getting to that point.
also check the earth on the bulbs because they wont work if there is no earth

This is a common problem. You didn't mention the type of vehicle you have and whether or not its one or both bulbs. At any rate, first make sure the bulbs are not blown, the head light fuses are not blow and that the headlight connectors are on. If all of those things are good there maybe a problem with the wires or the dimmer switch may have failed. You may need a wiring diagram to follow up with. I know that you will say that because the switch still activates the high beems, how could it have failed. The reason is because power for the low beams often travel thru this switch. Often times, this portion of the circuit can fail.

DIMMER SWITCH OUT OF ADJUSTMENT.I SEEN CAR WITH SAME PROBLEM THEIR HIGH BEAMS WOULDNT WORK.THE DIMMER SWITCH AND BULBS WAS GOOD.IT TURNED OUT TO BE DIMMER SWITCH NEED TO ADJUSTED.

Pull plastic cover off of column ck where wires mate to multi function switch and switch for traces of heat . More than likely switch is bad.

your flasher is probably bad, it is usely round and mounted close to the fuse box

Basicly lights operate from same source of power, so if you have high beems then power and ground should be intact. The operation of changing high to low is controlled by column switch,< blinker switch assembly >, and there slight possibility that both bulbs are actualy bad. To be on the safe side would check bulbs and wiring to them is in good shape before trying switch replacement.
