SOURCE: 1997 Chevrolet Headlight problem

We had the same exact symptoms right down to the clicking noise under the dash. A friend who is a mechanic provided all the wiring diagrams, etc and when we pulled the dash we found that there was another enclosure behind the dash.....we stopped there.......

....waited a few days, did some research and decided since a replacement headlight switch was about $50.00 the easiest route was to to swap that out hoping it would fix the problem....was also a very easy installation.

Turns out that fixed the problem. Good luck!!!

SOURCE: Headlights won't turn on. Daytime running lights stay on.

See if you can hold on your highbeams, as a temporary solution, until you can check and see if the fuse in the switch to turn your lights on is burnt out. I had the same problem with my car and apparently it was a defective part that GM had produced, but obviously they won't replace it free of charge. I would suggest going to an auto-wreckers and picking up a new switch there... the part usually costs around $400 in Canada.

SOURCE: headlights alternate on and off left and right daytime/high beam

although the underhood relay panel is common, I'd check your headlamp bulbs first, these are cheaper than the fuse box. The daytime running lights work off the high beam circuit, thus, a blown highbeam bulb could be the culprit, the fusebox solution was more common on 2001 and up modles, although it's a definite possibility.

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.

What causes the headlights to switch on automatically when you put the key on?


Your ignition switch is wired through a relay so the headlights will turn on automatically hope this helps

How disable Twilight on 99 Cadillac Deville


  • Examine the left dash panel to find the headlight switch. This is the control you use to turn the headlights on or off, with the exception of the daytime-running lights.
  • Look directly beneath the headlight switch. You'll see a small lever. This is called the "Twilight Sentinel." Move the lever all the way to the left to the "Off" position.
  • Turn the headlight switch to the "Parking Lights" mode. This icon has a symbol of two small bulbs. The daytime-running lights are now turned off.

    1998 Lumina lights don't work at night!The lights work during the day but not at night. Does anyone know how to fix it?


    Theres a sensor in the middle of the dash by the front windshield that detects sunlight and triggers the automatic headlights. The main headlights and daytime running lights might be on a different circuit, in which case they daytime running lamps would turn off at night and the main headlights would turn on, indicating the main headlights arent working and the daytime running lamps are working as intended.

    I would check all the fuses related to headlights, check the bulbs and check the switch, then last the light sensor on the dash.

    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 wont work properly


    Sounds like you have a problem in your headlight switch. As far as them staying on sometimes when you shut the car off are you referring to daytime running lamps or the regular headlights? If it's daytime running lamps that like to stay on and your headlights do not like to turn on then there could be a combination of headlight switch and daytime running lamp relay.

    It is possible the relay gets the signal from the headlight switch as well, since they generally turn off when you turn your headlights on.

    Daytime running lights work but go out when I turn headlights on. Ruled out headlight switch, bulbs, fuses, relay, ground, and DRL module. 98 silverado 1500 has no high beams. headlights work with parking...


    If you have daytime running lights but when you turn on your regular headlight on they do not come on. Take the bottom of your steering column off (Two Small Screws) and look at the back of your turn/dimmer switch make sure that the light blue wire is connected. The wires will break off after years of raising and lowering your steering column.

    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.
