On a 97 mercury the first thing i would check would be bulbs if the they are good it will most likely be what is called a multifunction switch turn signal,wiper and dimmer switch all in one always check on line before you go to buy one at auto part stores

Does the high beam work on `flash to pass' feature? That's when you pull the lever toward you to flash your high beams.
If they light up while you pull your lever, it's probably a bad headlight connection at the switch on the dash,OR a bad headlight switch(very expensive if it has the delay feature,which most of them do.
If your lghts DON'T brighten when you pull the lever toward you,it might just be bad bulbs......one goes out and you don't notice it, and then when the other goes out,you NOTICE it. don-ohio (:^)

SOURCE: no driving or high beam headlights

Hi,

To my knowledge a 2003 Toyota Camry uses a dual filament halogen bulb, either by Osram, Philips or Sylavania. If on the dashboard, the blue indicator lits when the switch is moved to bright or the passlight is engaged but no headlight, then it could jut be busted bulb (or part of it since you still have driving/low beam). In some cases, it could be the relay that supplies power direct to the bulb. At other times, it could be fuse(s) assigned to high beam. At certain instances, it could be also a loose, corroded or burned connector.

Corrective measure for your concern would be to check the 2 bulbs. This is performed by removing the rear covering (rubber or plastic cap) of the headlight assembly from the rear. The bulbs are held in place by a spring clip that needs to be unlatched from the base/holder. Carefully remove the bulb taking care not to touch the glass envelope. The filaments would be readily visible and cut/breaks would be apparent. If determined that one of the filaments (high beam) is open, replace the bulb(s).

If the bulbs prove to be OK, you need to work yourself backwards tracing the wiring harness. After the bulb, check the 3 prong connector for any corrosion or scorching/burnt marks; clean as maybe required. Next to check would be the relay that provides the +12VDC and then the fuse.

I doubt if the dashboard or steering wheel components involve with headlights may be at fault.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

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: 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

SOURCE: head light not working on high beam

When dealing with wiring on a vehicle, it can go from something real simple, to something real complicated, in a hurry!

1.Checked to make sure the headlights have high beam? Bulbs are good in that respect? Not trying to insult your intelligence, but sometimes it's the simple things we overlook. Again, not trying to sound 'Uppity', but do you have access to a type of jumper wire, that has a needle type of tip on both ends? This way you can stick the needle tip, into the wire that has 'juice' for the low beam side of the headlight, and touch the high beam side. See if the high beam comes on.

2.Sometimes it's as simple as a bad ground. There is a wire, or wires, that come out of the headlight wire loom, and have a rounded metal terminal end. A machine screw, goes through the hole in this rounded metal terminal end, and fastens it to the metal sheet metal of the body.

The metal frame of a vehicle, and the metal sheet metal, is the ground for a vehicle.
A lot of times, where this rounded metal terminal end is fastened to the sheet metal, (Or frame), rust can develop between them. Between the metal terminal end, and the sheet metal. This makes a bad contact for grounding.

There is enough of a ground source for low beam headlights, but not enough for the additional draw of the high beams.

3.In the headlight wire loom, there is a Fusible Link. This looks like a 1, or 2, or 3 inch large bump in the wire. This fusible link is designed to melt inside, and break contact, should it need to. Sometimes it's readily apparent when you view this fusible link. It will have the plastic covering melted on one side, or partially around. Sometimes it's not so obvious. (Isn't wiring fun(?)
You just have to use the probes, (Needle tip is real nice here), on a multimeter, (Set to DC voltage, and the 50 volt scale), and track from battery to headlight switch, to headlights.

4.Lastly, it may be the headlight switch itself.

SOURCE: 2001 Toyota Corolla high beam lights are not

Your switch must be working since your indicator is telling you when the high beams are on, so my guess is that your bulbs are faulty. The high beam part. They probably burnt out one at a time, so you didn't notice until the second one went. Change your bulbs, and see if that solves it. If not, let me know.

High beams not working on mercury marquis


you have a bad wire .....had the same problem with mine.what i did was took out the turn signal /combination switch from the left side of the steering column and put a test light to each of the wires to see which one went on and off when using the high /low beam switch.then followed the same color coded wire down near the bottom of the steering column and spliced a new piece of wire into it.then ran the wire through the firewall (just happened to have one already there above the harness that goes through the firewall).if you need to drill small hole for new wire make sure you feed a half inch of small vacuum hose into the hole before you run the wire through.this will prevent a short from happening.then go under the hood on the driver's side and between the master cylinder and the fender you will see a brown colored plug about 3 inches long and about 1 inch around.tap the new wire into the green wire and then try your high / low beam.it should be working fine.haven't had a problem with mine since.....good luck , DAVE B.

When I turn on my highbeams, the lowbeams shut off. Is this normal?


Yes, the low beams will shut off if you turn on high beam. Not sure which way yours work but if you push the lever for high beam, pull the lever back and all lights will come on or vise versa. You would think all the lights would turn on when going into high beam.

My blinkers have stopped working and my break lights dont work except for the light over the top of the back end. it works when i press the brake. my regular lights work and my high beams work also.


Fix. Turn signals and hazard are on one switch on the dash. Problem is cold solder joints on small board on the switch. First fix I re soldered loose connection on board, worked for a while. Finally simply changed switch with a new one. Take off dash. About 5 screws, pop out hazard switch replace. Problem solved.
