Had this same problem a couple of years back. I replace my signal switch because the hazard switch would not work and I quit having the problem. The switch seemed to have overheated.

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.

Headlamps
You can use the headlamps two different ways.
?€¢
Place the headlamp switch in the HEAD position for normal operations


?€¢
Place the headlamp switch in the OFF position for automatic lamp control (ALC) operation. During ALC the low beam headlamps are ON for daytime running lamp (DRL) operation in daylight conditions at reduced intensity or low beam headlamps ON at full intensity with exterior park lamps ON in low light conditions. 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 just the low beam headlamps at reduced intensity for the daytime running lamp (DRL) operation. A resistor wire is used (CKT312) to reduced the voltage which reduces the light intensity for the DRL's function. The ambient light sensor can also turn ON the low beam headlamps and the exterior lamps for automatic lamp control (ALC). Any function or condition that turns ON the headlamps will cancel the DRL operation (this means no reduced voltage to the low beam lights). Thirty seconds after you start the engine with the headlamp switch in the OFF position, the DRL will perform one of two actions:
?€¢
Illuminate the low beam headlamps at reduced intensity in daylight conditions


?€¢
Illuminate the low beam headlamps and exterior park lamps for low light conditions

The DRL operates when the ignition switch is in the RUN position, the parking brake is not set and the transmission is not in the PARK position When these conditions are met and the DRL ambient light sensor indicates daylight conditions the DRL will illuminate
Should have BCM scanned for DTC'S - diagnostic trouble codes , could have DTC'S stored in memory !
DTC B2645 Ambient Light Circuit
The body control module (BCM) monitors the ambient light sensor signal circuit in order to determine if the daytime running lights (DRL) or the auto headlights (ALC) should be turned ON in the AUTO mode. When the BCM senses the ambient light sensor voltage is between 1.75-4.9 volts, either the DRL will be commanded ON or the ALC will be commanded ON.

  2. Ensure that the headlamp dimmer switch is in the LOW position.

How to adjust headlights on 2013 dodge journey


Wahoo do is pop the hood, and there should be two-three screws around the headlamp assembly. These adjust the light directions. But you'll need to pull the vehicle away from a solid wall by about ten feet I think it is, and mark off a little area to adjust the lights at the correct level. You will be able to find this at you
ocal auto parts store. I usually go to Advance Auto, or Auto Zone. They have the little kit that helps you get all the marks on the surface you are using.

The left front low beam headlight does not come on. have replaced the bulb, but only hi beam works.


Since you've eliminated the headlight itself as the source of the malfunction, the problem is most likely the headlight bulb connector - the female connection inside the connector to the hi beam is good, but the connector supplying power to the low beam is bad. Your fix is to replace the headlight connector.
How: buy a replacement headlight connector at your favorite auto parts store, cut off the old connector, then (a) solder and heat-shrink or (b) wire nut and E-tape, or (c) crimp connector the new headlight connector onto the existing wiring (being careful to route the conductors to the correct wires on the connector).
Your cost: about $3 for a new connector

How to replace toyota matrix front headlight bulb


Hi,

Replacing a headlight on a Toyota Matrix is a simple process that only requires the use of a screwdriver and a replacement bulb. The Matrix uses 9006 bulbs for the low beams and 9005 bulbs for the high beams. Headlight bulbs can be purchased at auto parts stores.
Replacing Low Beam Bulb
  1. Turn off the engine of the Matrix and open the hood
  2. Rotate the bulb base in the headlamp assembly counterclockwise to remove the low beam bulb. Unplug the electrical connector. If the connector is too tight, wiggle it slightly to help remove it.
  3. Install a new bulb into the connector and place it into the assembly. Rotate it clockwise to lock it into place. Close the hood.
Replacing High Beam Bulb
  1. Turn off the engine of the Matrix and open the hood. If replacing the left-hand headlight, remove the air cleaner duct by removing the securing clip with a screwdriver and pulling the duct out of the vehicle.
  2. Turn the bulb base counterclockwise to remove it. Unplug the electrical connector.
  3. Install a new bulb into the connector and place the bulb into the assembly. Rotate it clockwise to lock it into place. Reattach the air cleaner duct if replacing the left-hand headlight. Close the hood
I hope this helps.

Best regards.

Daylight Running Lights


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.

Installed new low beam headlight and light will


Hi, if you have a meter to check the bulb, use it to check the wiring to the socket or wiring for power when light switch is turned on. You should have around 12 volts depending on year and type of truck or auto. If the old bulb was burned, you should have power there. When you turn on switch, the other side should work and you will know you have power and it may just be corroded. Check this and you should find the problem. Please keep me posted on this, I will be around to help you. Please rate me kindly if I have been of help to you.
Sincerely,

The headlights do not activate automatically, in the auto mode, at night or with minimal daylight. However the running lights will activate in the auto mode. A new dash light switch was installed without...


The light sensor to control the automatic headlamps is located on the dashboard. This sensor is suppose to activate running and headlamps. I would suspect the problem is a relay to operate the headlamps if the car uses a seperate relay in the automatic mode. I'm assuming the headlamps work in manual on/off. FYI... The auto mode does not control the fog lamps.

How to replace low beam bulb on 2004 baja


I was able to locate an owners manual for the vehicle. The large plastic weatherguard protecting the headlight bulb connections needs to be rotated CCW about 90 degrees, and removed to provide access to the bulbs. Then remove the center connection for the low beam and release the spring clip retainer to release the low beam bulb. Replace with new bulb and reconnect/reinstall retainer clip, center connector wire, and weatherguard. Note that this is the procedure for the Turbo Baja...non-Turbo model is different.
