Press the dome light 4 times. It has an override inside that shuts them off or on if you do that.

Your headlamps are controlled by you Body Control Module (BCM) The FIRST thing I would do is scan the BCM for fault codes. It is possible that the DRL relay is stuck in the ON position, which would override your request for regular driving lights, or the BCM may not be receiving the signal from the headlamp switch that you are requesting regulat=r driving lights. The ONLY way to find out for sure is to check the data in the BCM and operate the switch and see if the BCM changes the status of the "Headlamp Request" or "Headlamp Switch" PID. There are two relays on the headlamp circuits, one is for the POWER side of the headlamps and the other is for the GROUND side of the headlamp circuits. The BCM controls the ground side through the Multifunction Switch (dimmer, wiper, turn signal switch).
The headlamp switch controls the Power side relay and also sends voltage to the BCM to tell it that it has turned the power on to the headlamp power relay.

In any case, replacing parts without scanning the BCM is the EXPENSIVE way to go about performing this repair.

SOURCE: i got a 2004 chevy

If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

Daylights not working


10A fuse 16 in the central junction box supplies power to the DRL module. 15A fuse 15 in the battery junction box (BJB) supplies power to the DRL relay. DRL module output passes through 15A fuse 12 in the BJB and 15A fuses 2 and 3 in the BJB and is applied to the headlights. If all fuses are OK, the problem may be in the DRL relay, the DRL module or associated wiring

Daytime running lights not working


Assuming this is an LX, check 7.5A fuses 9 and 5 in the driver's underdash fuse/relay box. Fuse 9 applies power to the DRL indicator light in the gauge assembly which connects to the DRL control unit. Fuse 5 supplies power to the DRL control unit when the ignition is on. Also check 100A fuse 41 in the underhood fuse/relay box which supplies power to the headlight relays. Setting the headlight switch to HEAD causes the headlight relays to close and apply power through 20A fuses 45 and 43 in the underhood fuse/relay box to the low beams. Low beam power also passes through the DRL diode to close the high beam cut relay and prevent high beam use during DRL operation.

I need to know were to find the DRL Module for a 2003 F-150 4x4. My hi and low beem lights work ok , and the auto light sencor works . Its that my Day time running lights do not come on .


The wiring diagram does not show a stand alone drl module for the 03 f150. However it shows 2 drl
relays located in aux. relay box #2 located behind the right side of the dash, left of the glove box.
Also there is the drl resistor located behind the grill, right of the left headlight. Relay #1 is fused at
fuse #5-15a in the fuse block under the left dash. Relay #2 uses fuse #26-10a under left of dash.
Hope this helps.

I have a 2005 Nissan Altima 2.5 S. headlights are not working....


Does your car have daytime running lights? It may be the drl module. The relays are part of the IPDM (intelligent power distrubution module) and are not serviceable. If the drl module is faulty the symptoms are, no drl, and one or more lights not working. Usually not grounding within the drl module.

My r/f high beam is out, so I replaced the bulb but I still have no high beam. Also my daytime running lights stopped working, could they possibly be related?


Yes your daytime running light just uses the headlight bulb on a lower voltage so if the headlight is not working the drl will not work as well, they are dirrectly related,,check the head light fuse,and check to make sure the bulb is good,,

Both Headlights Work On Lowbeam But Not On Highbeam.


First identify if your day running lights (DRL) are working. The DRL and high beams will work on the same relay. If your DRL are working, but not your high beams, you may need to replace your high beam relay which is found in the fuse panel under the hood of the engine at the right back corner; near the firewall, and passenger tire strut mount. If there is also a problem with your DRL with the high beams, its likely the DRL relay which can be found tucked under the dash.

There's usually a cover that says "relays", "fuses", etc. Lift the cover and look underneath, it should label the relays. If not, consult a manual or repair book. Try swapping similar relays from know working accessories if you don't have a new one handy.
