    I meant daylight running module. Its not anywhere near the coolant overflow tank that some people have been suggesting on line.

    id bet its a Canada export car, made for the Canadian market. the FSM book shows, it , if its not there then the car is modified. so just find all wires that go to lamps that glow, in DRL mode. keep in mind wire colors also change for Exports, due to laws in THEIR country. and big time change if to Europe. see wiring page, 8w-50-2 and page 7, see the factory wiring. see the colors, page 7 is the canada page. if you read that page, you can see the DRL (mod) fits between the HL and HL switch, the module has 7 pins,wired. and one is low beam and is DRL pin 10 and is (canada) color code VT/WT (violet -white stripe). so how many models on car are at lest 7 pins, and with that color wire, ONLY ONE. if your car is not stock then nodody hear can help you. we tell to follow THAT color wire, or we can tell you , that the wires that look hacked are in fact hacked, do you know what that means. non OEM type wiring hacks, ? (we can show a list of 100 hacks) but why do that. all techs, know stock wiring, with factory connnectors, do you know about that?

    one more point, USA, only, EPA laws. open hood, look up, behold the big white sticker (shows vacuum map and timing rules) and shows what country this car is for. plain as day, it will say, Mfg for USA regulations conformance. bla bla or USA fed and Calif , or only calif. or for Canada with a oak leaf sticker for canada EPA compliance, all cars in USA have that sticker by law.

    The jeep was built for sale in Canada. I've had it 14 years. Befor that my father owned it for 5 years. I have a complete maintenance history of the vehicle. This is the first thing that has ever gone wrong with it electrically.

  • Terry Welsh Apr 16, 2014

    Thanks Fossil! The Jeep was built in Michigan, USA. It was bought brand new in British Columbia, Canada. It came with running lights and it is a left hand drive.

    ,oops the market code is not in the vin, its on the body code plage. , the FSM chapter that covers this , is named, INTRODUCTION, page 2, BODY code plate. open hood, its on the top left side of Radiator Reinforcement brace. it has 1 to 7 lines of data. bottom line is #1 line. and has 3 digit tanny code, the 1 letter market code (bingo) and then the VIN at end. then the market code. U-C-B-M (this tells the market (target) to be sold. this is all that matters, this one letter. this one leter changes what you read on every page in the FSM. now I will decode this.

    as i said, Canada allowed gray market cars, until 1998 so only this code matters.. if you bought a USA car, then it was retrofitted with and Aftermarket DRL (manyt types). (required in canada)

  • _-__-___-_
    _-__-___-_ Apr 16, 2014

    when you buy a car in USA its got a U code, in canada, it can be other codes. My guess is that the car is not C code. the USA car as a lamp outage module, at left quarter corner time panel. and overloads if traile lights are added illegally (over 5amps) the LAMP chaper covers that, the DRL it say (factory) has an internal circuit break and autoresets in 60seconds , a key factor in diagnosis.

  • _-__-___-_
    _-__-___-_ Apr 16, 2014

    Im reading that same , LAMP chapter, now, page 7 and it shows DRL module , directectly below the PDC, the PDC is the underhood main fuse box. the USA car also has an autohead lamp on ,module (and options) so on some GC, Headlamps can fail for 3 models. and the usual. HL, switch/fuse./wires.

    Bad news Fossil. The jeep was in an accident in 2000. It has all the wright stickers on it, but nobody transfered the body code plate. Thanks for all your help, it is greatfully appreciated. If you have any ideas I would be greatful. Other than that keep following this. Iwill let you know what I find. I have some work to do to fix this. Once again THANKS.

    bummer.. but if that DRL connector, in the harness below the PDC, if that is missing, ,it's a USA car, (U-code) and is not C code , canada car, so that means, its hacked, that is , the DRL is not STOCK but is aftermarket, that fact puts you, reading ever black box on car, (oem or not?, say to self? ) 1 by 1, or follow the lowbeam wire, see that color, it goes to an aftermarket, DRL box. , find that box, then get the name off it and p./n and you have a path to sucesses.

    my guess car is in Canada. why not just say so?
    "The running lights stay on ." key OFF.
    Headlights on? key off, my guess NO.
    or all park lights, front rear, and side markers stuck on??? ill guess, yes.
    The park lamps (aka. tail/park/sidemakers)
    can stick on only if , circuit L90 sticks on.

    this can be the head lamp switch stuck on
    or the DRL pin2 stuck on.
    when pin 2 sticks on pull fuse 24,.

    see the drawing below, and pin 2.

    real book shows.
    see pin 2 on the module.
    and fuse 24. ?
    it must hot be HOT, (means 12v)
    when the key is off.
    is it? using a voltmeter? check all DRL pin voltages... all of them. and report.

    Fuse 24 kills the lamps. now.?
    1995 ZJ,
    questions , do you have automatic headlights option?
    below is real ZJ DRL box. for canada only.
    does pulling fuse 24 stop the park lamps
    from glowing?
    if yes, that means the drl box is bad
    or the logic inputs are wrong. to it.
    to see if the logic is bad, use a voltmeter
    on all pins on the DLR box.
    the module is show below, next to PDC.





  • _-__-___-_
    _-__-___-_ Sep 19, 2015

    the 3rd pin above from left is pin 6
    if that pin is hot, then the DRL will mess up
    that is the headlamps on switch , or stuck in park.
    that pin 6 line is L26 signal.

    _-__-___-_ Sep 19, 2015

    my guess, is pin2 is stuck hot. (logic)
    and pin is stuck hot.
    if not pin 6 stuck hot the DLR is bad.
    my guess2, is the DLR box has relays inside.
    (old technology and like to stick.)
    remove it? and smack it sharply, not break case hit it , to jar loose any contacts inside stuck.

Where is the DRL module located on a 2003 GMC Savana 1500?


There is no DRL module .
Daytime Running Lamps (DRL)
The DRL are a function of the front turn signal lamps. The DRL will operate when the ignition switch is in the RUN position, the gear selector is not in the PARK position, and the headlamp switch is in the OFF position. When the BCM receives these signals it will signal the turn/hazard flasher module to turn on the DRL by grounding the DRL low control signal. The turn/hazard flasher module supplies voltage to the DRL on the right and left DRL/turn supply voltage circuits. If a front turn signal lamp is inoperative the DRL will not operate.
The DRL can be deactivated by turning the headlamp switch to the DRL OFF position while the DRL are operating. The DRL defeat position of the headlamp switch is a momentary ground signal to the BCM to command the DRL function ON or OFF. After each key cycle the BCM will default to the DRL ON function.

I need clarification on 2003 Chev Malibu DRL problems:


That piece you think is a ceramic DRL module is a resistor , When in DRL mode voltage to the low beam headlamps circuit goes through that resistor dimming the headlamps from low beam to daytime running lamps . It sounds to me like you need a new resistor ,but without doing some electrical testing it could be a lot of things . The DRL relay in the under hood fuse box could have a problem , could be the BCM - body control module , the ambient light sensor etc... Here is how daytime running lamps work .
Daytime Running Lamps (DRL)
The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level. When the BCM receives this signal it will either turn on the daytime running lights (DRL) or the headlights. Any function or condition that turns on the headlights will cancel the daytime running lamps operation. With the headlight switch in the OFF position, the headlights will either be turned ON or OFF, after an approximate 30 second delay depending on whether daylight or low light conditions are sensed. The HTR A/C IGN fuse in the underhood junction block supplies ignition positive voltage to the daytime running lamp (DRL) relay coil circuit. The DRL relay switch contacts are connected to the low beam circuit. When the headlamp switch is placed in the OFF position, the BCM will either turn on or off the daytime running lamps, depending on whether daylight or low light conditions are sensed. The BCM energizes the DRL relay, closing the switch contacts and grounding the low beam circuit. Ground is provided at G101. The DRL illuminate the low beam headlights at a reduced intensity. The DRL will operate when the ignition switch is in the ON position, the gear selector is not in the PARK position and the parking brake is released. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.

Where is the DRL relay located?


There is no DRL relay , has a lamp control module .
The daytime running lamps (DRL) activate under the following conditions:
?€¢
The ignition switch is in the RUN position.


?€¢
The ambient light sensor indicates daylight.


?€¢
The vehicle is not in the PARK position.

When the above conditions are met, the lamp control module (LCM) supplies battery positive voltage (B+) to the low beam headlamps through CKT 589 (GRY), the DRL resistor, and CKT 12 (TAN). The DRL resistor reduces the voltage supplied by the LCM. The low beam headlamps light at a reduced intensity. The DRL disable if the vehicle is placed in the PARK position. When the ambient light sensor indicates darkness, the low beam headlamps automatically switch from a reduced intensity to a regular intensity.

2002 Grand Prix heater/lights, My heater randomly works and if the heater doesn't work either does my head lights. I'm thinking it's my ignition switch?


If you mean that the Daytime Running Lamps (DRL) does not work when the blower motor does not work, then YES it COULD be an ignition switch problem. However, not very likely (please read on). The regular HIGH and LOW beam headlamps do not require the ignition switch to operate.

The main circuit that runs your regular headlamps also runs the blower motor HIGH speed. This has nothing to do with the ignition switch.
This circuit also operates the Power Mirror circuits and the Hazzard Flashers. You may want to check to see if these are also malfunctioning when this happens.

The Circuits for your other blower speeds go through the ignition switch along with the DRL control module, but your HIGH speed does not. So if it is your ignition switch, your HIGH speed should still work and your regular headlamps should still work. You will lose only your lower blower speeds and DRL if it is an ignition switch problem. You will have a bunch of other stuff going out if it is an ignition switch also. The ignition switch circuit that runs your DRL module also runs your Powertrain Control Module. So if it is an ignition switch problem causing your DRL to shut down, your engine will also be shutting down.

Daytime running light module location 2001 impala


The daytime running lamps in your 2001 Chevrolet Impala are controlled by the Body Control Module (BCM) Here is a description of how the system works:

The ambient light sensor is a light-sensitive transistor that varies its voltage signal to the Body Control Module (BCM) in response to changes in the outside (ambient) light level. When the BCM receives this signal, the BCM turns ON either the DRL or the headlamp relay for auto headlamp operation. Any function or condition that turns ON the headlamps will cancel the DRL operation.
Thirty seconds after you start the ignition with the headlamp switch set in the OFF position, the DRL will perform one of two actions:

Illuminate the high beam headlights at a reduced intensity in daylight conditions
Illuminate the low beam headlights in low light conditions
The DRL/EXT lamps fuse in the top of the engine fuse block supplies battery positive voltage to both the DRL switch contacts and to the DRL relay coil. When the BCM energizes the DRL relay coil, current flows through the right high beam lamp, to the left hand high beam lamp, to the energized DRL relay switch contacts, to ground G101.
The high beam headlamps are now in series, and split the voltage so that the headlamps illuminate at halt intensity. The DRL operates when the ignition switch is in the RUN position, and the parking brake is not set or the transmission is not in park. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.

Hi, Have an 88 Olds Cutlass Ciera. High beams come on, but won't stay on more then 10 seconds. Low beamd did work, but now flash on and off. This may or may not be related. Short in tail light , the fuse...


MOST VEHICLES HAVE A CIRCUIT BREAKER BUILT IN THE HEADLIGHT SWITCH. OVER TIME THE CIRCUIT BREAKER WILL GET WEAK & IT WILL TURN THE HEADLIGHTS ON & OFF. YOU PROBABLY NEED A NEW SWITCH & THE FUSE BLOWING IN THE TAIL LIGHT CIRCUIT MAY BE A SEPARATE ISSUE.

Head lights wont turn off after turnning off car


See if you have fuse under dash or under hood if more fuses in there that is marked DRL , or DRL module. (daytime running light module) may be at fault. Pulling that fuse may isolate problem, otherwise you may have to pull connector off back of light switch to test it.

Where is the module for the day time running lights on a dodge ram B 1500? 1996


Notes CIRCUIT OPERATION - CANADA
On Canadian vehicles, the low-beam headlamps operate when the ignition switch is in the RUN position and the headlamp switch is OFF.

When the ignition switch is in the START or RUN position, circuit A1 from fuse 15 in the Power Distribution Center (PDC) connects to circuit A21. Circuit A21 powers circuit F18 through fuse 19 in the fuse block. Circuit F18 feeds the Daytime Running Module (DRL) module.

Circuit L20 from the headlamp switch connects to DRL module. Circuit L20 is HOT at all times.

The DRL module receives the vehicle speed sensor input from circuit G7. Circuit G34 from the DRL module provides power for the high beam indicator lamp in the instrument cluster.

Circuit L4 powers the low beams of the headlamps. When the headlamp switch is OFF, the DRL module powers the low beams on circuit L4. When the headlamps are ON, the multi-function switch powers the low beams on circuit L4.

Circuit L3 feeds the high beams of the headlamps. When the operator flashes the headlamps with the stalk of the multi-function switch, the DRL module senses voltage on circuit L3. When it senses voltage on circuit L3, the DRL module stops supplying power to the low beams on circuit L4.

Circuit Z1 provides ground for the DRL module.
