I have the answer to your question about troubleshooting your headlights on your vehicle. I would isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illunimates with the headlight switch on. Good luck!
check the wires, and check the fuse for your lowbeams. could of blown a fuse on your lows, but your highs will still work.
Every single time I have had a failure of low beam in a headlight without failure of high beam, it has been because the lamp bulb or halogen lamp module has reached the end of its serviceable life, not because of any wiring problems. Low beam burns out first because it is on the most. If low beam is lost simultaneously in both headlights, I would check fuse first, then the headlight switch. If low beam is lost on one side only, it is almost always going to be due to the bulb or lamp module needing to be replaced. In that case, replace them in both headlights because the other one will be going kaput in short order, as well.

CHECK THE DIMMER SWITCH.THAT IS THE PROBLEM MOST OF THE TIME.
Measure for voltage at the light bulb clip first. It could be a bad set of bulbs. If you have no voltage, check fuses, and then check for voltage before the headlight switch. It could be a faulty headlight switch. Measuring a few voltages will tell you what the problem is.
Change the headlight bulb. 99% of the time it is the bulb that is the problem.
Most definitely check out the headlight dimmer control switch .... Ron J.
the lamp is probably bad easy to check look at it. hi beam light do carry more current and tend to fail sooner
Lowbeam is an H7, highbeam/DTR is also H7
The circuit requires the hi/lo switch. You'll need to get a replacement switch for everything to complete the headlamp circuitry.
I'm having the exact same problem. Does anyone know what is causing this?
I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages. I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages.
I am actually having this problem.. here is mine... see if it relates to you. My headlights (on regular, low beam) do not work. I cannot get them to come on in the high beam either. But, if I pull the blinker arm forward for the passing flash thing, they light up on high-beams (only for as long as I hold the lights on). I have found the problem to be a thing called "Multifunction Switch". My car is a 1997 Ford Taurus G.... See if that helps you any. It was my underlying issue and mine is getting fixed tonight. :) Good luck
both my lowbeam headlights aren't working although high beam and parking lights do. probably aloose connection. any ideas how i can fix it sal
If both lowbeam headlights fail at once, it probably isn't the lamps themselves. That would be a fluke. The wiring is usually not at fault. It is vulnerable at the ends where the connectors are because they might become corroded. Check that last. That leaves the two other vulnerable points in the circuit: the fuse and the light switch. Check them out.
Just replaced the headlight bulbs in a 98 Grand Cherokee that had the same problem. It had the wrong bulbs in it. It had 9007's in it. Calls for 9004's.
It is possible that both of the fuses are bad for the low beam headlights and the cruise control. A loose ground wire could cause the fuses to blow.
just behind the headlamp lens assemblies you'll find little plastic doors that you open to access the bulbs,.... pay attention to the location of the lowbeam bulb lens before you open the doors or you'll be replacing the highbeam bulbs. it's straighforward from there--just unplug the old bulb, plug in the new one and shut the little plastic door.
Should be coming out of the wiring harness on each side of the car, where the harness is fastened to the radiator support. The ground is bolted to the radiator support on both right and left sides near the headlights- on the back of the radiator support
Most can be replaced by you fairly easily. See your owners manual. For a rough idea on what the price is on the actual lamps, see sources and related links below.
It cn be the switch, bulbs or wiring. I suggest if you intend to work on your car to get a shop manal on it from AUTOBOOKSONLINE.COM for about $20
For 1986 Vanagon: 1. Remove plastic grill - 5 screws. 2. Remove entire metal cage surrounding light - 4 screws. 3. Unplug highbeam and lowbeam lights. 4. The white plastic things sticking through 3 of the 4 holes can be tapped out gently with a hammer, hitting the white plastic from the front.
Making any modifications to the electrical system on your car could be dangerous. To obtain proper advice either contact a local dealer or a specialist auto-club.
The manual show it in the back but I could never find the screws to which the manual refers. Here is what I did. The replacement lowbeam lamp only fits correctly one way, with the tab on the top. I kept inserting the lamp, removing, and bending the tab until the beam was'aligned' properly.
blown fuse/blub on the lowbeam is pop/wiring is messed up
1) Open front hood. 2) Twist lowbeam connector from back of headlight casing. 3) Twist apart bulb from the connector. 4) Replace with new bulb. 5) Reverse order of above steps to finish.
Turn your headlight switch to the "on" position. disconnect the power wires from the bulbs and use a volt meter to find which ones have voltage. if your highbeams are off, then the wires with voltage are your normal driving lights. the ones without power are your highbeams. also. positive and negative don't really matter with lights. just so long as there is current running through the fillament. there is usually only one way the plug will fit the lights anyways.
I had this problem on an '02 525i. The socket in the wiring plug was corroded. Replaced it and no problems since, over 1 year now.
The bulbs screw in from the rear and if you can't get to the rear, you have to take the light assy off.
PULL the light switch out (must be in lowbeam setting for fog lights to work)
Could be, but I think your Low beam light bulbs might have just burnt out. Also it could be like me your wiring might have a short... If you do have to replace the lowbeam bulbs and you notice within a 3 month period(or less) that the lowbeam bulbs go out, you might want to have a professional examine your car. My lowbeams go out alot since the original bulbs burnt out. As I drive alot at night I allowed for the extra usage (I'd never done so much night driving). Within 6 months I'd burned out 4 new bulbs...
Open Hood. Open the hood of your Mazda 5. The hood release is located under the dashboard of your 5.
The fog light switch is located to the right of the radio. Why I have no idea. It's under the rear window defrost and wiper controls. It's just a funny looking button with the light symbol with some lines beside it. The fog lights will only come on when you have the headlights on LOWBEAM. Switching them to hi turns them off. I'm sure there's a way around that but I haven't had mine long enough to find it.
