    Both headlights operate this way so it can not be a loose bulb. High beams do come on if switch lever is pulled for passing,

Headlights only work when car is in gear


If you are stating the headlights only work while in gear (during the day or night) then they are your daytime running lights. Don;t know if you vehicle has automatic headlights or a manual switch. If you are stating you turn the headlights on and they only illuminate while in gear then there are other issues. Let me know

Automatic headlights don't work all the time on 1999 Buick Regal GS with 144,000 miles. Intermittent problem. Sometimes they work and sometimes they don't. I always keep headlight switch on middle...


hi,
you had specified as, the headlights are not working properly & making a buzz sound.The problem is the circuit has a loose connectivity either at the switch or near the bulb. while you are able to hear the buzzing sound check the position of the wires near the source of sound. You will be able to find where the connectivity should be tightened exactly.please do this as early as possible since the loose connection can damage the circuit and the switches due to high temperature.
thanks, have a nice day.

Headlights will not come on, either automatically or manually. at one time it was intermittent, now nothing!


have you tried looking in your fuse box? it is unlikely that both your headlights are out at the same time but a blown fuse would cause this.

Headlights won't come on intermittently 2005 Dodge Caravan


Quite possibly the switch, Dodge minivans also have a front control module located under the hood, it attaches directly to the underhood fusebox, if a switch doesn't fix it I would look there.

Dash lights go off intermittently


I'm no expert, I recently purchased a 2003 vibe. I noticed the automatic headlight's sensors can be super-sensitive, about an hour hours before dusk they'll kick my headlights on (when the sun is still shining!), or sometimes when I go into an underpass, and then sometimes they'll realize it's light enough and turn themselves off. This would cause your dash lights to go to the 'headlights on' mode and turn the headlamp signal on, the intensity is controlled by the dimmer/dome light control on the left side of the dash. Check to see if the dimmer is down too far, as this could cause the lights to dim when the automatic headlights turn on. It's also possible that the dimmer is not working, thus no power is getting to the dash lights through the dimmer. Try testing it by starting the car in daylight, then manually turn on the headlights, then adjust the dimmer. Like I say, I'm no expert, just guessing because I've noticed it happen similarly on my Vibe, but my dimmer was at half-way, as I like it for night driving. Someday, I'd like to disable the automatic sensors and DRL.

2001 Pontiac Grand Prix GT multifunction switch problem?


I had the exact same problem, I changed the "ignition switch" because the contacts inside were burned, this is why you see all those troubles coming in and out at different moments. It costed me 150$ to do it myself, buy the switch on an online reseller, must cheaper than the dealer! Now everything is back to normal on my Grand Prix GT 99 exept that my headlights don't light up automatically when starting the car... I have to check my fuse/relay and switch to make sure everything is ok on that side.

Good luck.

2001 Pontiac Grand Prix GT multifunction switch problem?


The multi function switch is the turn signal switch. It also does control wipers and lighting. If you are having the issues you describe then you will most likely have a body control module problem. Before you spend the money to buy the module and get it programed get it checked first. Goot Luck

1997 jeep cherokee headlights quit working at the same time and will not come back on.


check the position of the automatic headlights switch. If it is placed in the auto position and the road becomes lit then the lights will go off automatically. Before condemning the switch try placing in it on the other positions. If the switch works fine, try checking the headlights relay, there are two relays (one is for the automatic headlights)
