Daytime Running Lights Module Defective?

My dash lights fuse keep blowing and the headlights are always on DRLM "mode". The dash HL switch makes no difference to lights when the car is running, they are on with the DRL module, but if the dash switch is in the on position (running or headlight position), the car keeps running when the key is turned off. High beam stalk switch will not switch the headlights to high, and seems to have no effect at all.
Can the DRLM fail in this fashion?
Thanks

I suspect you have a bad ground somewhere. Try this - remove the headlamp bulbs and see if he car stays running. COuld judt be a shorted headllamp bulb.

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.

High beam indicator comes on with fog lights


Could your Mazda have daytime running lights? If you checked all fuses, did that include the three in the joint box?

There is an auto light-off control module that is central to all functions you describe. It is assumed that you would only turn on the fog lights with headlights on and set for high beam. If you set the headlight switch to LOW, the module closes the headlight relay to turn on the low beams. If you then turn the headlight switch to HIGH, the module turns on the high beams and allows you to turn on the FOG LIGHT switch, closing the fog light relay and turning on the fog lights. Since this sequence is not working, I suggest checking both high beam lamps as both could be burned out. Other possibilities are a defective headlight switch or the module

The headlight stay on all the time, either daytime running lights or all lights. The car has a sensor bulb in the dash. If you pull the headlight switch on and then push off, they still stay on. Trying...


This sounds like how the headlights on this vehicle are designed to operate. They can be manually turned on if in DRL mode. Setting the park brake before turning the ignition on should keep them from lighting, otherwise they are always on. The light sensor switches between lowbeam and daytime running light modes.

Headlights and dash lights are flickering. Pleae help.


First check your baterry terminals, make sure they are clean and secure.
If it's your daytime running lights that flicker, check the DAYTIME RUNNING LAMP MODULE

1998 Firebird dash light and running lights...


There is a module under the dash that controls the Daytime Running lights or DRL. It might have something to do with it. You can find some more info here:http://www.chrisnovoa.com/166_camarofirebird-drl-module-color-codes

Also all that lighting goes thru the headlight switch. Try unplugging it and putting the fuse in. If it still blows its probably the module.

1997 Chevrolet Headlight problem


did you try removing the DRL fuse to disable the daytime running lights, and double check your bulbs and fuses for the regular headlights? I'm not much of a mechanic but I'll take that fuse box before messing with anything else.
