Why would running lamps quit, left headlight is very dim DRL light on dash flashing?

Right headlight is normal--new bulb makes no difference--left headlight fuse OK. Swapped bulbs left to right etc. same problem so bulbs are OK. What next?

    I am wondering if your ballast is going bad. I will look into this a bit more.

    I cannot see where you mentioned the make or model or year. You may have, I am just beat up tired. Can you add that info, because if it is an older car they don't have ballasts. Thanks!

    1996 Pontiac Sunfire GT. It's not the alternator--one headlight is fine and the problem stays constant when bulbs are exchanged. DRL's quit at same time as the left headlight went dim.

    Ok cool. I have a friend who is an automotive electrician. I will pass this info on to them and get back to you-- promise. I know what a pain it can be when "things" are just going wonky. I will get back to you tomorrow. Hopefully, it isn't anything to crazy. I am sorry to say that Hondas are my forte, I really know those persnickety beasts, but I do have another question: Do you headlights have individual ballasts? It is a smallish box that sits behind the headlight. With Acuras, when a headlight does this, it means the ballast has given up.

Have your alternator checked yet? Your alternator is what actually powers all of your devices and lights when the car is running. When it is failing it will cause lights to dim. Checking connections, fuses and your alternator should lead you to a good start! Good luck!

If headlights don't come on on a 2000 Buick Lesabre what do you think is wong


first go for the easy stuff. do the tail lights come on? if so, then will almost guarantee it's bad bulbs in headlights. if tail lights do not come on I would check fuses first relay second. switch third.

My turn signal fuse blowed got new one now they dont work why


canada or USA, (diffr. laws, different wiring, even DRL up there)
station wagon or NOT?
THE TURNS FUSE BLEW OUT. 2nd time, 3rd,,,?????
that means the circuit is overloaded or shorted.! (prevents fire)
but did it blow a 2nd time, why not say so???

all 4 lamps dead. or stuck on, or flash odd. or what? dim?
does the cluster lamp flash, , in blink or emerg. mode?
wont work , means what, (dead or stuck on or dim)?????
do emergency flashers work? ,dead, stuck on what?
does car drive perfect day or night?
are any other things on car dead, of odd acting?
we see all this , 1st 5 min in a shop, zero here.
ive answered Forenza blinks here, many times.
ever search?

ill now answer by guessing USA non stationwagon and no DRL.
dash box fuse 4 kills blinkers

EF1 (engine fuse) 1 good?
dash fuse 14 and EF1 can kills emerg. flasher

so of Emergancy flash lamps blows fuse 14,(smaller of 2)
then the blinkers are in fact shorted.
does it?
if yes, then find out which side blows the fuse 3.
turns left blow or turns right blows.
so if say turns right blows, F4 fuse.
if true ?remove all bulbs front rear right bulbs.
does the fuse hold now,(means not blown)
then buy new lamps there. problem solved
bulbs can in fact short.
not just blow open.
Tell the full story and all this gets easy.
For sure emergency flash,

Dim head lamps and day light running lamps won't come on my 2000 Buick lasabre


Daytime Running Lamps
With the daytime running lamps (DRL) programmed to be on, the DRL will operate when the ignition switch is in the ON position, the gear selector lever is out of the PARK position, the headlamp switch is in the OFF or PARK position, and the ambient light sensor indicates daytime conditions. Battery positive voltage (B+) is supplied to the DRL relay coil through the underhood fuse block. Battery positive voltage is supplied through the underhood fuse block FOG/DRL Fuse to the DRL relay normally open contact. The DRL relay normally closed contact receives ground for normal high headlamp operation. When the dash integration module (DIM) determines that conditions are right for the DRL, the DIM grounds the DRL relay coil. This energizes the DRL relay coil and closes the switch to the normally open contact. Battery positive voltage (B+) is supplied to the LH and RH high beam headlamps in series. The high beam headlamps split the voltage and each lights at half intensity. Current will follow the path from the DRL relay to the LH high beam headlamp, HDHIBML Fuse, HDHIBMR Fuse, the RH high beam headlamp, then to ground.
Does your vehicle have
Twilight Sentinel
The twilight delay switch in the headlamp switch is supplied a reference voltage from the instrument panel integration module (IPM). It is supplied a reference ground from the IPM. The switch is a potentiometer that resistance varies as the switch is moved. The IPM receives an input voltage proportional to the resistance of the potentiometer. The IPM sends a class 2 message to the dash integration module (DIM) indicating the on/off status and delay length for the twilight sentinel. With the twilight sentinel in an ON position, the DIM will automatically control the headlamps on/off status depending on the nighttime/daytime status of the ambient light sensor. The DIM will use the twilight sentinel delay length to know how long to keep the headlamps and park lamps on after the ignition switch transitions from ON to OFF during nighttime conditions.
If you don't know about these things you best bet is to take it to an ASE certified repair shop or the dealer .
If you

Hello,I use honda accord 2004model,(EOD) the DRL life is on,yello lite,pls explain better to me.thanks


in canada? with DRL?
is the charge (battery Light on running)
nice photo but do name all lights, i see idle is at 800rpm good.
i see check engine light there, top left. so you need to scan PCM
using any scan tool
that is first.

DRL can shut down for other failures one is charge lamp. on.
if charge lamp is on , do not drive far, or it will stall and battery will discharge and be stranded. (till AAA auto tow is called <jumped)

No headlights on dim only work on bright


old post.(day)
low beams, they are.
both low beam lamps.dead but are PARK/tail dead too?. (a key fact needed here to save time finding cause)
there are more that one cause.
but fuses are first, some cars have 2 fuse.
one for highs and lows.
or for left and right.
they do that so at least some lights work and not all go out at once, on a dark rainy night on a country road (or cliff road)
GEO, the car brand GEO is sold mostly in USA and Canada
if in CANADA the law says its DRL lamps.
in canada they have a Drylight Running lamps and laws and have a unique controller for that (DRL module) and can fail and mess up lamps. so GOT DRL>?
on this car the fues box shows, left and right HL
the next question is does it run a relay.
answer,
DRL, the DRL module runs low beams totally so that be first.
and its DRL relay.
non DLR metro, works like this
im reading the online schematics for you, and so could you.
the no-DRL is brutally simple.
the fuse runs the lamps direct, means lamps hot all the time.
the park and head light switch, grounds the low beam wire feed.
no relays , magic , DRL just a simple switch, in the combo switch.
for you or others seaching Metro head lamps.
here is the schemo.
red/wht wire must be 0v on low beams if not switch bad.
if g200 is good, but g200 is used in highs so can NOT BE BAD.
as you can see the switch grounds the HL lines below.
to make the lamps GLOW,

Cant this DRL module cause the headlights and day light running lamps to quit working. For a brief period, I could use daylight running lamps sometimes in place of my headlights when they quit working. Now...


Do you have tail ligts and side marker lights with drls on? if so you will have only dim headlights. Check fuses, I think the headlights are fused seperately.

99 silhouette.all bulbs are in working order.right (not left) signal flashes fast when headlights are on and even worse when brakes depressed(lights on or off).also lights on both rears are real strange on...


I had similar symptoms - rapid flashing of directional when headlights on and brake depressed when making a left turn, both directional indicators in dash light dimly when brake depressed, "Check Traction Control System" indicator On even with ATC turned Off and "strange" indications in tail lights.

Check the pins in the connector at the Lamp Holder Assembly for your Rt. Tail Light for arcing and corrosion. (The female pin is in the vehicle harness connector and the male is part of the Lamp Holder Assembly.) If found, because the male connector is part of the Lamp Holder Assembly, you'll have to replace the Lamp Holder Assembly and the harness section coming in from the vehicle containing the female connector.

I just repaired this problem in the left tail light on my '01 van with a part from a '99 van I found at a local salvage yard.
