2000 Chevrolet Silverado 1500
The day time running lights do not turn on during the day. The headlights and parking lights come on during the day and at night. The truck does not have an auto headlight / daytime running light option.
Terry Dyess, yes. Headlights are on instead of the DRLs. kmgraham4, even the base truck has the auto headlight/daytime running light as standard. DRL sensor, relay, bulbs, sockets, wiring and main headlight switch as well as main wiring have to be eliminated.Terry Dyess, yes.

In the 1999 Chevy Silverado 1500, the headlights are not designed to be on all the time by default. They are typically controlled manually by the driver using the headlight switch, although some vehicles may have a daytime running lights (DRL) feature. If the headlights are continuously on, it could be due to a modification or wiring issue, and it's recommended to consult the vehicle's manual and seek professional assistance if needed.
If the fuses are good, I would check for power in and out of the headlight switch. The parking lights and dash lights are on two different circuits but controlled by the headlight switch.
There is a light sensor that tells the truck if it is night or day on the dash. Make sure that is it not covered up. If is is not then you may have a bad sensor. It sounds like the sensor is telling the truck that it is night every time the truck is running.
Start the tuck with the park brake on to see if the light come on when it starts. If they do you have a bad relay if not it is most likely that sensor on the dash.
Not saying that you don't know this but the daytime lights are turned off in park.
If that is not your problem, a friend of mine uses the amber bulbs, they last longer.
.Lights only come on when vehicle is in drive. There is no switch for it. If the lights still dont work check the bulbs,They go bad all the time and you may find a bad light socket. When you pull the bulb out the socket will look burnt and probably need replaced.I run into this problem frequently. You have to replace the bulb with the same number bulb you have .
The day time running lamps are your headlights, the parking lights also conventionally known as the running lights serve no purpose during daylight hours and as such are not necessary in the daytime, and are not illuminated by the DRL module. The DRL (Daytime Running Lights) module illuminates the headlamps in a slightly dimmer state than night time dim headlamps, but does not turn on the conventional running lights. The only way you'll get conventional running lights during the day is to turn them on manually. I just reviewed the wiring schematics for that system, and the DRL relay bypasses the dimmer switch when active and prevents high beam operation, and feeds current directly to the low beam headlights, there is no connection to the parking light circuit from the DRL module wiring.
When you say you replace the fuse 3 times, is because the fuse have blown? If so, there is a short in the system and will need expert help to trace the short.
Does the day time running light stay on during day light hours and does the lights comes on without activating the headlight switch during night hours when the park brake is released?
If so, this of course is normal condition. If not then the day time running light circuit needs diagnosing along with the body module circuit. Headlight switch will also need to be tested.
Do the headlights come on at all.
Terry Dyess, yes. Headlights are on instead of the DRLs. kmgraham4, even the base truck has the auto headlight/daytime running light as standard. DRL sensor, relay, bulbs, sockets, wiring and main headlight switch as well as main wiring have to be eliminated.
