SOURCE: low beams on head lights not working


I had this problem.
In Canada all cars come with daytime running lights- (DRL) My 2004 Kia Sedona had this problem and it was the DRL Module.

Serach internet to find it's location. ( I think it is under the centre console, but dealer changed under warranty)

It should not be hard to find and change - It is usually just a small plastic box... plus or minus the size of a fist.

I don't know if DRL is required in the USA but it may be standard on Kias

SOURCE: Kia Rio5 headlights won't come on. I have marker

The low/high settings of the headlights is switch on via
an electrically operated relays. These relays are connected to the fuses. Therefore, check the relays if these are working properly, as well as the fuse where
these relays are connected. These should solve your problem. You may get in touch with us via e mail for
further assistance. God Bless you.

Each light has its own fuse. Have you checked them? Maybe try switching two of them to see if they swap which one works... Once in a while a fuse that looks good has actually gone bad. Comment on this post if this doesn't help and we can move to the next step. Good luck!

SOURCE: headlights & dashlights turning on & off

Daytime running light module which is located under dash (around the area of the fuses) probably has a bad solder joint inside (if you take it apart). If not could be bad connection on one of the switches (like your dimmer switch)

Low beam headlights do not work 2010 chevy impala high beams work as do daytime running lights low beams do not work on either automatic mode or manual mode

The headlamps are controlled by the BCM - body control module , do you know what that is ? The headlamp switch is a input to the BCM ,the BCM energizes relays to turn on the headlmps , low beam relay , high beam relay , DRL relay . These relay's are PCB - printed circuit board relay's ( non - serviceable ) If found to be bad the whole under hood fuse box would need to be replaced .
Low Beam Headlamp Operation
The low beam headlamps may be turned ON in 3 different ways:
• When the headlamp switch in the HEAD position for normal operations
• When the headlamp switch is in the AUTO position, for automatic lamp control (ALC)
• When the headlamp switch is placed in the AUTO position, with the windshield wipers ON in daylight conditions, after a 6 second delay
Battery voltage is applied at all times to the coil and switch sides of the LOW BEAM PCB Relay located in the underhood fuse block. When the headlamp switch is placed in the HEAD position, ground from G202 is applied through headlamps ON switch signal circuit to the body control module (BCM), signaling the headlamps ON request. In response to this signal, the BCM applies ground through the headlamp low beam relay control circuit energizing the low beam relay. With the relay energized, battery voltage is applied through the switch side of the relay, the left and right low beam fuses, and the low beam supply voltage circuits illuminating the low beam headlamps. Ground for the left headlamp is provided at G101 and the right headlamp at G100.

Do you know what B codes are ? BCM - DTC'S - diagnostic trouble codes , need a factory scanner or professional one to view these codes , not autozone or advance etc....Having a qualified repair shop check your vehicle would be your best bet.

DTC B2575 00: Headlamp Control Circuit

Circuit/System Description
The vehicle headlamps are controlled by the body control module (BCM) based on inputs from the headlamp switch and the turn signal/multifunction switch. The headlamp switch has four positions: Off, Auto, Park, and Headlamps. The default headlamp switch position is Auto, in which the BCM uses the ambient light sensor to determine when headlamps are needed. The Off portion of the headlamp switch is a momentary switch which overrides the automatic headlamps and will turn off the vehicle headlamps. When in the Off position, the headlamp switch grounds the headlamp switch headlamps off signal circuit, prompting the BCM to turn off the headlamps. The Park position of the headlamp switch will only illuminate the vehicle parking lamps. The Headlamp position of the headlamp switch will illuminate both the parking lamps, as well has the headlamps. With the headlamp switch in the Headlamp position, the headlamp switch headlamps on signal circuit is grounded, prompting the BCM to turn on the headlamps, regardless of other factors such as ambient light.
The headlamp high beams are controlled through the flash to pass switch and the headlamp dimmer switch, both located in the turn signal/multifunction switch. The flash to pass switch is a momentary type switch, designed to illuminate the high beams as long as the switch is held. With the switch closed, the flash to pass switch signal circuit is grounded, prompting the BCM to turn on the high beam lamps. The headlamp dimmer switch allows the operator to select between full time high or low beam operation. Unlike the flash to pass switch, it is not a momentary switch. When the headlamp dimmer switch is in the high beam position, the headlamp dimmer switch high beam signal circuit is grounded. This prompts the BCM to turn on the high beam lamps.
The BCM controls the headlamps based on the inputs explained above. When a low beam request is received, the BCM grounds the headlamp low beam relay control circuit. This energizes the coil in the LOW BEAM PCB relay, causing the relay switch to close. This then applies B+ to both low beam headlamps through the LT LO BEAM and RT LO BEAM fuses, illuminating the low beam headlamps. When a high beam request is received, the BCM grounds the headlamp high beam relay control circuit. This energizes the coil in the HIGH BEAM PCB relay, causing the relay switch to close. This then applies B+ to both high beam headlamps through the LT HI BEAM and RT HI BEAM fuses, illuminating the high beam headlamps

Left operating headlight not working

the switch supplies power to the relays that switch on the lights according to the position you have it at
so on high beam there will be 2 high beam lights working
on low beam there will be 2 low beam lights working
back to passing lights or flashing head lights , both beams will work so the switch is the last item to consider
Now with only one side beam not working it comes back to the ground on that light for that bulb
remember that electricity follows the path of least resistance so it the ground is bad the current will ground out through another point including a light which will switch that light off or make it not work
remember the brakes light that flask when an indicator is used --same thing

Low beams not working

If the bulbs flash when you unlock the vehicle, then they are likely not the issue. My guess is the relay contacts are dirty. Just because a relay clicks, it doesn't mean that it is passing current through the contacts. Try and swap the relay with another of the exact same part number. There's usually another the horn relay, fog lamp etc..

Headlights I have a 2001 impala my head lights are not working on low beam. I have replace the relay fuse still nothing. lamp switch does not come on. I have a day time mood an this is not working until I...

Pulling on the turn signal switch is called "flash to pass" and you are activating the high beam lights.
Have you checked to see if you have power in and out of the dimmer switch on low beam ?

Check the headlight relay, and check for loose connection. Unplug the headlights, and see if you get some voltage while the switch is on. Low voltage reading indicates a loose connection. Listen for a relay if it clicks when you turn it on. Pull out the relay open it, and check the contacts for signs of arcing characterized by burned apearance.

High-low beams not working

Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.

Kia Optima 2005. no low beams

Check the low beam relay . Look here for location Enter vehicle info. year , make , model and engine size. Under system click on electrical distribution , then under subsystem click on relay . Click the search button then the blue link . Look at left side near the bottom ,HEAD LP LO . Right above #5 and #4 fuse's . Do you know how to test at relay base ,that's where it plugs into.

Kia optima low beams

First verify that the switch is energizing the relay in both positions by turning the low beams on and then pulling up the relay--does it click? If not, replace the switch. If yes, next check for power on the red wire as it comes out of the column. Switch on, no power--replace the switch. If power, check for power at the head-low fuse in the engine compartment fuse box. No power--find break in wire. If power, check for power on the yellow/red wire as it comes out of the fuse box. No power--repair fuse box. Power--check for power at lamps--same wire. No power--repair yellow/red wire.
