SOURCE: LOW BEAM LIGHTS

Hi Rich Million,

Check the bulbs for the low beam problem and if they're ok, check the fuses under the bonnet (hood) which are found in the fuse box. If you've already checked those, go to the fuse box inside the vehicle.

Still no luck....remember that there are fuses and relays inside the cabin behind the kick panel.....You may find that there is a problem with the main fuse box.....If you drive over rough terrain, check the connections under the main fuse box....even if your roads are all smooth, it's still worth checking.....

SOURCE: low beam headlights not working on 2004 Pontiac Montana extended

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.

I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

SOURCE: high beams dont work

Could be that your high beam light's are burnt out and need to be replaced. When you say the the switch is new you mean the lever on the stearing collum is new right?? Good luck

What you have sounds like a Headlight SWITCH Problem, You can check the Fuse for them (DOUBTFULL) but its a Large one @ Power distribution Box Under Hood.

Where is the headlamp relay on a 2007 saturn ion


Are both low beams an high beams not working ? What engine does your car have ? Low beam relay only on 2.2 L .
On vehicles with manual headlamps, the LH HDLP and RH HDLP fuse in the fuse block - under hood, supply battery positive voltage to both low beam lamps and high beam lamps at all times. The low beam and high beam circuits continue through the fuse block - under hood, through the body control module (BCM), and to the headlamp switch. The low beam or high beam circuit then, depending on the position of the dimmer switch, continues through the headlamp switch. When the headlamp switch is placed in the ON position, it provides a ground path for the low beam or high beam lamps through G203. The low beam and high beam circuits are monitored by the BCM.
Is there B+ voltage at the headlamp fuse's ? Power runs from fuse through the head lamps to the dimmer switch through the head lamp switch to ground when turned on . If there is B+ voltage at the fuse ,check for voltage at the headlamp switch .

Replaced the head lamp bulb but only works on high beam


Make sure the other filament is good and that it is receiving power. If no power check relays, fuses, switches,etc for low beams.

Were is headlight low beam relay


It is located in the under hood fuse/relay box . It's non -replaceable ,if bad whole fuse box has to be replaced ! 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.
Low Beam Relay Test

  1. Ignition OFF, disconnect the C2 harness connector at the underhood fuse block.
  2. Connect a test lamp between the control circuit terminal A5 and B+.
  3. Ignition ON, command the Low Beams ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
  4. ?‡'
    If the test lamp is always ON, test the control circuit for a short to ground. If the circuit tests normal, replace the BCM.


    ?‡'
    If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

  5. If all circuits test normal, replace the underhood fuse block.
  6. Ignition OFF, disconnect the harness connector at the inoperative low beam headlamp. Test for less than 5.0 ohms between the ground circuit terminal B and ground.
    ?‡'
    If greater than the specified range, test the ground circuit for an open/high resistance.

    Connect a test lamp between the supply voltage circuit terminal A and ground. Ignition ON, command the Low Beams ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
    ?‡'
    If the test lamp is always ON, test the supply voltage circuit for a short to voltage. If the circuit tests normal, replace the underhood fuse block.


    ?‡'
    If the test lamp is always OFF, test the supply voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the underhood fuse block.

    If all circuits test normal, test or replace the low beam headlamp.

When dimmer switch is turned to high, the two high beam only light up, the low / high main lamp goes off.


It is normal that when you select high beam that the two high beam lights come on and the low beams switch off. the light position should show high beam
It goes off on low beam when the high beam lights go off and the low beams light up
If the light is reversed then check the wiring to the light
You didn't mention what car it is but if it has a light module then the problem may be in it.

2001 ford ranger , no high or low beam lights


Check the On/Off switch on the dash, steering column, and the steering arm/lever is connected properly and that the lighting cable's are cable connectors are connected and not corroded.
1, To check the Earth: Connect a cable from the earth of the bulb to the chassis/body/ metal part of the car.
2, Using a Test lamp: Disconnect the cable that connects the power to the head light bulb, Connect one end of the test lamp to any one of the connectors at the end of the cable that plug's into the bulb. With the low beam on, only one of these wire's will the light switch turned on will light up the test lamp bulb. If none of the cable's light the test lamp bulb. the problem is in the High beam relay, and possibly the Low beam relay as well.
One Head lamp relay: If one cable show a light in the test lamp, check the earth cable on that lamp.
Two Head lamp relay: If two cable's show a light in the test lamp, check the earth cable on that lamp.
Some of the car's electrical systems use the Steering column as an earth point. Check the switch.
In many cases are what is called Earth return (this means that the positive power (+) is supplied by one wire, and the negative earth (-) is connected via another wire) this is to reduce the problems of the rust effecting the power flow.

Main beam lights not working


check fuses, in cab and eng. bay.
high beam or low beam.
main to me, is low?
do you want to guess or diagnose?

do you have a voltmeter? a DMM or DVM. ?
with a meter, this is easy.
are both headlights dead?
does car have DRL? (in canada many cars have this, do you?)
Daytime Running Lights.?
the 2003 USA model, has a Relay control module under hood.
in your car all lamps are grounded and 12vdc power feeds
the lamps via 1st the control module then 4 fuse to the lamps.
as you can see 4 fuses, usually dont blow at once.
inside the module are 2 relays. one for low beam and one for high beams. they too can fail. so if lows are bad, replace the low relay.
if you get the FSM book for your car, its ALL there, ever fact on
this simple circuit and how to test it.... step by step.
never buy a car, with out the FSM, if a DIY person.
if not? take it to the man.....

Well the high and low beam lamps use the same fuses, and the dimmer switch handles the ground circuit. So I would check the dimmer switch if both high beam bulbs are ok.

My high beam lights & parking lights work, but not the normal lights.1985 holden astra!


By "normal lights" I assume you mean "low-beam headlamps"? If this is true, then you may either have burned out headlamp bulbs or a faulty low-beam headlamp relay or relay circuit.
