Where is the DRL - Daylight running light - module on a 1998 Ford Escort? Mine don't work and I'd like to check the fuses and relays.

USA car,? or not or Canada, sorry they are not all the same
DRL on the car? daylight running lights Y/N???
check all fuses first.
scan the PCm
check the DRL module for burnup's. seen many.
head lamps work key on and key off by law ,USA.
High and low beams dead that is 4 lamps.
car drives normal and no other electric failures??????
look for HL relays yet.

this a CANADA car with loves to fail DRL lamps (daylight running lamps)>>
`
hood open switch dead kills many things on some cars even starting engine dead.

my guess now is , DRL died as they love to do
and you need a new DRL module see its burned up pins?
it is more simple this year, and no DRL modules to burn up as seen 1996 on many here.
clean the sunset sensor lens of all dirt.??????
more
there is a DRL relay too
and these words.
DRL operation is determined by the ambient light sensor and the controlled by the body control module (BCM)
paste more me
BCM determines the conditions are met for DRL operation, it applies ground to the DRL relay control circuit energizing the DRL Relay. With the relay energized, battery voltage is applied through the switch side of the relay, the DRL fuse, and a resistor wire spliced to the low beam supply voltage circuit illuminating the headlamps at a reduced intensity. Any function or condition that turns on the headlamps will cancel DRL operation. When the BCM detects low light conditions, it will turn OFF the daytime running lamps and turn ON the low beam headlamps as described above in Low Beam Headlamp Operation. The BCM will also turn ON the low beam headlamps in daylight conditions when the windshield wipers are turned ON.
all this and more in the service manual
there is no dRM module actual
just BCM and 1 relay here it is, seen in real book on 2006

all fuse con are works
headlamps work key off and on.
park lamps work key off too. do they
the BCM is told to go to DRL mode with the sunset solar cell devices
that hardwire BCM
your shop is using? 1996 scan-tools are useless on his GM car.?
cant see DTC P1xxxx errors up or blind to B2575? errors
all B25xx errors the tool can not see GM real modern errors/
sad that if true.


one trick after all fuses checked
and battery main ,rested, is 12.6vdc fully charges
pull the battery neg lug for 30min. or 1hour and put it back all the brains reset and can now function ok.
the transmission may do to auto-learn model , no worry there.
clean the sunset sensor. lens.
and use only modern scan tools say 2005 up or newer.
for sure those marked GM ready !!!!!!!!

DRL relay ?
The daytime running lamps (DRL) lights are controlled by the body control module (BCM) via the DRL relay when the headlamp and panel dimmer switch is the AUTO position.
The relay is feed by the IGNE fuse when the ignition switch is in the run and crank position, (the coil side of the relay), and the DRL fuse which is hot at all times. The DRL relay is controlled by the BCM based on the input form the ambient light sensor via CKT 592.
The relay supplies current to the lights through CKT 545 and ground through CKT 150 and ground G100.
The DRL lights are on when the vehicle ignition switch is in the run position, park brake is not set, daylight conditions exists and the transmission has been in drive before placing in park. The DRL lights are turned off when the headlamp and panel dimmer switch is turned to the park or head position or the input to the BCM from the ambient light sensor signals that daylight conditions does not exists any more.
The automatic lamp control (ALC) system and the DRL feature can be temporarily disabled by performing the following procedure:
Note: The ALC and DRL cannot be turned off on the Canadian vehicles and some early production vehicles.
Turn the ignition to RUN.
Press the DOME OVERRIDE button four times within six seconds.
A chime will sound informing you that the system is off. The system will remain disabled until the ignition is cycled off and then on or by pressing the DOME OVERRIDE button four more times within six seconds. The chime will sound again signaling that the system has been reactivated.

Behind the lower kick panel on the passenger's side good luck colin

Have you had vehicle check for DTC'S diagnostic trouble codes . Check fuse's an relays , find wiring diagrams to see what controls these systems ?
Radio/Battery fuse , fuse G 10 amp located in the right instrument panel fuse box . Do you know where this ?
Fuse Block - Right IP - On the right side of the instrument panel
An there is one on the other end of the instrument panel ,driver side .
Fuse Block - Left IP- On the left side of the instrument panel The fuel an temp . gauges not working is probably the step motors inside instrument cluster . GM had problem with this 03 to 06 .

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.
DRL operation in Manual Transmission equipped vehicles will occur when the ignition switch is in the ON position, and the parking brake is released. - check fuse's an relay first.

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 .

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.

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.

COULD BE DIMMMER SWITCH .DRL RELAY LOCATED IN FUSE RELAY BOX UNDER THE HOOD IN ENGINE COMPARTMENT.

The Module for the DRL is most likely bad, the DRL Module is squarish in shape and Black in color and would be located in the fuse area or in the engine compartment. Just pull it straight out and purchase another one and re-install. Buying new low-beam lights will not solve the problem, because if your low-beams work when you turn on your headlights than it is not your bulbs. The DRL Module uses your low beam lights, but at a lower intensity than when it is normally on, so if your low beams work when you turn on the headlight switch than your DRL Module is bad.

Could be the relay for the DRL is just stuck on. I assume you checked under your hood in the fuse box
