Its More Than Likely The DRL Resistor Is Cracked. Its In The Front Bumper Just In Front Of The Left Front Wheel Behind The Plstic Wheel House Cover. Remove The Cover, Its The White Ceramic Loop w/ 2 Wires Going Into It. Make Sure The Connector Is Not Damaged, Corroded or Full Of Water When You Disconnect It. If It Is, You Will Need To Replace It As Well. When Replacing The Connector Fill The Connector w/ Dielectric Grease, This Will Help The Connectior Stay Cooler

Where is my relay and fuse location at for the day time running lights on a 1997 oldsmobile aurora


There is not a separate fuse nor is there a relay ,A LCM - lamp control module controls the DRL .
the lamp control module (LCM) supplies battery positive voltage (B+) through the DRL resistor to the low beam headlamps. The voltage drop across the DRL resistor causes the low beam headlamps to light at a reduced intensity. The DRL are disabled if the high beam headlamps are on or if the gear selector is placed in the PARK position. When the ambient light sensor indicates darkness, the low beams automatically switch to regular intensity.

No low beam. Good high beam. No day lights. What's wrong?


No on the fuse . The LH HDLP and RH HDLP fuse in the fuse block - under hood, supply battery positive voltage to both low and high beam lamps at all times. For manual operation, when the headlamp switch is in the ON position, the headlamp switch supplies ground directly to the headlamps and to the body control module (BCM) on the headlamp low or high beam signal circuit, depending on the position of the headlamp dimmer switch. The BCM uses this signal to determine if the conditions are present to illuminate the daytime running lamps or park lamps.
The headlamps may be turned on 2 different ways. First, when the driver places the headlamp switch in the ON position, for manual operation. Second, with the headlamp switch placed in the OFF position activating automatic lamp control (ALC).For ALC operation, the BCM receives a signal from the ambient light sensor indicating a low or high ambient, outside, light level. Under low light conditions the BCM grounds the headlamp relay control circuit energizing the headlamp control relay. The now closed relay supplies ground through the headlamp switch to the headlamps and the BCM on the headlamp low or high beam signal circuit, depending on the position of the headlamp dimmer switch. When the BCM grounds the headlamp relay control circuit it also grounds the park lamp relay control circuit illuminating the park lamps. The headlamp relay is grounded at G203.
Daytime Running Lamps (DRL)
The low beam headlamps operate at reduced intensity when in daytime running lamps (DRL) mode. The ground circuit to the switch side of the DRL relay has a resistor in-line to reduce the intensity of the low beam headlamps for DRL operation. The body control module (BCM) receives a signal from the ambient light sensor indicating a low or high ambient, outside, light level. Under daylight conditions the BCM grounds the DRL relay control circuit energizing the DRL control relay. The now closed relay supplies ground directly to the low beam headlamps and to the BCM on the headlamp low beam signal circuit. The low beam headlamps now illuminate with reduced intensity. The DRL relay is grounded at G203. Any time the headlamps are illuminated the DRL will not illuminate. Manual park lamps do not effect DRL operation.

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,

Multifunction Switch Short in Pontiac Grand Prix


Do you know how to do automotive electrical testing , checking B+ power and ground circuits , using voltage drop ? Do you know how to read a wiring diagram ? Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia
Electric Testing Techniques You Need to Know

How to read an electrical diagram Lesson 1

http://www.bbbind.com/free_tsb.html find wiring diagrams here !

The day time running lights module , ambient light sensor , would be a good guess but that's all it would be .Do you know what these are ? Really don't think there is a short in the multifunction switch . Maybe it's time to take to a qualified repair shop , dealer ! Cadillac or Buick .

Daytime Running Lamps (DRL)
The Daytime Running Lamps (DRL) control module is designed to automatically operate the exterior lights depending on the outside light conditions.
The DRL control module operates in 2 modes:
• The day mode
In the day mode, the DRL control module turns ON the low beam headlamps at a reduced intensity when the DRL ambient light sensor detects daylight under the following conditions:
- The ignition switch is in the RUN position.
- The headlamps are OFF.
- The park brake is OFF.
• The low light mode
In the low light mode, the DRL ambient light sensor detects darkness, turning ON the low beam headlamps to full intensity through CKT 10.
Additionally, the DRL ambient light sensor turns ON the following lamps through CKT 9:
- The park lamps
- The side marker lamps
- The license lamps
- The tail lamps

I tried to disable DRL but when i did my low beams dont work, any ideas?


You are wasting your time. This system is automatically controlled by the Daytome Running Lamp module. The system requires the daytime running lamp relay to work in order for the low beam headlamps to work. Any attemps to "disable" the daytime running lamps will also disable the low beam headlamps. I think what you are having problems understanding is that your headlamp switch does not actually turn the lights on. The switch only provides power so the DRL module can operate....it doesn't send power directly to the lamps. The power to the lamps is provided by the relay, which is operated by the DRL module. Unless you want to completely "re-engineer" the ENTIRE headlamp system, you are not going to get it to work the way you are wanting it to.

I have low beam but no high beam. relay on new harness is good but it connects to the old harness. i put the new harnes on so i could have high beam on drivers side it worked for a while but stopped. most...


What relay's ?
The instrument cluster controls the headlamp systems that include daytime running lamps (DRL). The system allows the headlamps to operate at a reduced intensity when all of the following conditions apply:
• The engine is running.
• The transaxle is not in the PARK position.
• The normal headlamps are not on.
The instrument cluster turns the DRL system on by grounding CKT 592, thereby energizing the DRL relay. This action allows a reduced voltage of 6 volts to flow across the headlamps. If the vehicle has the optional fog lamps, the fog lamp relay will also be energized. The park lamps will turn on and the fog lamps will operate normally. When the headlamp switch is turned to the ON position, the instrument cluster allows normal headlamp operation.
The instrument cluster also has an input from the park brake. If the park brake is in the ON position, the DRL will remain disabled until the park brake is placed in the OFF position. On vehicles with an automatic transaxle, the instrument cluster will disable the DRL until the transaxle has been taken out of the PARK position.

Day time running light problem


The problem with the DRL issue describd in the above posts is the DRl module(it needs to be replaced). The buzzing relay and intermittent on/off of passenger side DRl are indicators that the module needs to be replaced.

Day time running lamps


The day time running lamps are your headlights, the parking lights also conventionally known as the running lights serve no purpose during daylight hours and as such are not necessary in the daytime, and are not illuminated by the DRL module. The DRL (Daytime Running Lights) module illuminates the headlamps in a slightly dimmer state than night time dim headlamps, but does not turn on the conventional running lights. The only way you'll get conventional running lights during the day is to turn them on manually. I just reviewed the wiring schematics for that system, and the DRL relay bypasses the dimmer switch when active and prevents high beam operation, and feeds current directly to the low beam headlights, there is no connection to the parking light circuit from the DRL module wiring.
