    I cleaned up the grounds. I now think the problem is deeper. The fuse was shot on the driver headlamp. However, it still was shining dimly. Replacing it fixed the headlamp, but why would it shine at all with a bad fuse?

    You have a bad headlamp ground on the driver side headlamp. Trace the white & black wire to the ground point, and make sure that it is grounded properly. Let me know what the wire and the ground looks like.

For some reason, Toyota chooses to wire their headlamps differently than domestic cars, with dual fuses for the headlamps, and a common ground for each headlamp...The reason that the lamp was dim is the bulb was getting power thru a "backfeed" condition, due to the poor ground. The fuse may have blown due to the poor ground, also.

If headlamp blub is good, check ground wire to headlamp and clean conection at headlamp plug, its possible you might have to run a new ground wire to headlamp.

SOURCE: Dim Headlights/headlight problem

if that is the case i believe your altenator is bad and draining the battery the altenator runs the engine and charges the battery the battery starts the vehicle and runs all the electronics and accessories the regulator is not working and therefore the battery is not getting charged and as the vehicle is running and the lights are on they will get dimmer and dimmer until there is no voltage left in the battery. reploace the altenator and the problem will go away...please rate this

SOURCE: On dim all four headlights are on, but the inner

first i would want to know that all the headlamps are in good working order. it kind of sounds like these are also bad bulbs. you will also need to look for good ground wires just behind the headlamp assemblies. to answere your question, YES. if things were not repaired properly and without attention to detail then you could have wiring issues. on the plus side it doesnt sound too difficult. try these items first.

remove both bulbs from the lamps but leave them on their wires switch on and see if the bulbs are still different brightness if not they the passenger side lamp housing has damaged mirror is dirty or missalined and needs adjustment. if they are different brightness then this may be a earthing problem.

Re Clarion radio screen brightness, I have retro fitted the radio to another vehicle but the wiring diagram doesn't mention a dimmer. Do I need to hook one of the wires into the headlights?


One of the wires on the radio is for the brightness. Connect this wire to one of the dash lights that dim with the dimmer control or the headlight switch dimmer if your vehicle is equipped that way.

I have a 2002 dodge grand caravan the headlights. One works on dim and the other works on bright. I've replaced both headlights and it did not fix it. What do I do next?


Sounds like a wiring problem. You may need a repair book to track it all down. Could be a ground connection too.
The headlight switch sends power to the dimmer, then thru the body control module, then the high and low beam relays, then the four fuses, then the actual headlights. So you should have power on the low or high beam fuses depending on which way the dimmer switch is positioned.

Headlights wont work on dim, only bright


Check your head light bulbs, your truck has the dual filiment headlight bulbs one per side which does both high beam and low beam, 9007 bulbs.
If the low beam filiments are burned out only the high beam will work.
Also look into finding out if the headlight switch is gone bad.
The headlight module and or drl module maybe defective.

The dimmer switch on my 1999 firebird won't change the headlights from dim to bright, or vice versa. It has a good click to it and the blue light in the dash comes on when they're supposed to


That is a common problem, the switch needs changing if the high and low beams do work, the only problem is that it's an expensive part to replace, try a local wrecking yard they should have a bunch of suitable replacements at a reduced price.

One head light lamp light is dim


If the headlights were not changed at the same time the dim one may be about to go out. If you change the dim one and not both of them the other one will most likely get dim while the other is still bright

1985 Nissan pickup- All headlights test good. On


Sounds like your ground wire is broken (which could be broken, overheated, loose or corroded) If the color of the copper has changed(looks gray) or is corroded then you must replace the plug.
