assuming the 2000 is same as 2001-2002, the headlight system runs upon firing engine and they stay on... doesn't make sense , if headlights work during day light and don't during night time,check your light switch , move it around , wiggle etc.. if no diff. , check head light sensor and did you know there are like 3 or 4 diff. fuse box's , there is one in the dash!!!, driver side i believce , good luck
IF you have an automatic head light module (Day night operation) check that the power when in the night mode is getting to the display. It may have it's own light sensor that turns on the display light and if so it may be faulty as well.
Are you sure there not running in daytime running light, when you think high beams are on
Also, there is sensor on the dash, usally on the speaker grate, that senses night and day. In the daytime your headlights will automatically come on when your car is in drive, and be on the high beam bulb, but dimmer than regular. At night, or in low light conditions, your lights will automatically switch from daytime lights to regular low beams. And yes, even when your switch on the dashis turned off, your lights work automatically.
To turn of the auto setting, just push the override button for your dome light, in and out 3 times, you should hear a chime, and your lights should shut off. This setting resets everytime you shut your vehicle off. Or to turn the auto setting back on, push the over ride button 3 more times.
I have a 1997 cadillac deville that has both 'daytime running lamps' when put into gear and 'twilight sentinel' which turns the headlamps and parking lamps on at night, and goes off during the day or when it is bright enough.
There is an adjustable delay for the twilight sentinel to turn the headlights off after the ignition key is removed and it is night time.

I had the 'daytime running lamps' installed on a 1990 Cadillac Deville that turns the headlamps only on when the ignition key is switched to on with an aftermarket module. The headlamps are about 70% or so as bright as the regular twiilight sentinel headlamps and parking lights and are designed to go on during the day.
The twilight sentinel overrides this feature when it gets dark outside.
I had the daytime running lamps installed by an auto electric shop that specializes in electrical systems, alarms, stereos, etc.
you have day time running lights you are supposed to manualy turn them on at night. if you dont manually turn them on,on most cars the tail lights are not illuminated the automatic headlamps only turn the head lamps on. and they are controlled by the sensor located in the middle of your dash board
Well you know the problem, go for it, replace the head light.
In the future, this is how it works.
Pull the E brake up before you start the car.
When you put it down the geen day time light will flash three times then the repair light will come on.
That means you have a burned out head light.
