Daytime Running Lamps are automatic if you have the car turned on, in gear, the parking brake off and the ambient light is bright enough to not trigger the automatic switch. If however the car is on, it's in gear, the parking brake is off and the ambient light is bright and the day time running lamps are still off then you may need to just turn your headlights off. If that doesn't fix it, you may have a bad resistor, a burnt out light, a burnt out fuse or bad wiring. The first three are easy to fix. The last is not.
When daytime running lights do not work, it means the bulbs may have burned out. It could also mean the fuses have failed or there is a short in the wiring.
There is a fuse for these lights. I would highly recommend not doing this as it is illegal.
Hit 'em with a big hammer
Cheapest returnable answer is to remove the bulbs
If the Explorer is running engaging the parking brake is supposed to turn the daytime running lights off , otherwise the daytime running lights are supposed to shut off when the engine is shut off . I have a 2004, Eddie Bauer Explorer. On the light switch itself, there is a selection to turn on or off the day lights, as well as the extended, courtesy lights after ignition is turned off.
Remove the fuse on the interior fuse box
Turn headlight switch to the left to turn off daytime runnig lights. Turn switch back to left to turn back on.
check your fues
unplug the main fuse.???easy or the sensor behind the grill.
you have to remove the drl module that located in the fuse box...
My 2004 Endeavor does not. However, I like the idea, and the lights turn off when the ignition switch is in the lock position, so I leave the headlights on all the time.
