A good place to start is your fuses and then check the actual lights. I had that problem too, it might be the DRL module under the dash to the left of the ash tray. careful, its next to the airbag lines. it would be about the height of your right knee, if you seated in the drivers seat. a small metal box about 2"x2" dark brown or gray color with one wire plug in it. its kinda hard to get out and its not cheap.
They are daytime running lights. They are always on so people can always see you. Its a safety thing. Newer trucks have specific daytime running lights.
daytime running light module under drivers side dash
If emergency brake is on 1 click it turns daytime running lights off. Pull out on emergency brake handle and see if this fixes the problem.
there is a relay under the hood that should disconnect the daytime running lights
I have a 1999 chevy Silverado how to fix my day time running lights
NO , Not from the factory.
The daytime running lights are connected to the bright lights. It just reduces the power for the daytime runners.
DRL = daytime running lights
The whole headlight on these 03 silverado is not that hard to take it out. When you pop the hood open as you look on the headlight there should a long piece of tube metal that is holding the headlight onto your car. As I recall there shouldn't be any screws or bolts holding the headlights. That is for headlights, not "Daytime Running Lights". Still looking for answer!
Just remove the DRL fuse in the fuse box, If your wanting to turn lights off while driving.
yes , by removing DRL
When daytime running lights do not work, it means the bulbs may have burned out. It could also mean the fuses have failed or there is a short in the wiring.
Running light bulb replacement is simple on the Chevy Tahoe. I just did it today on my 2000. Follow the easy and well written instructions in the vehicle manual under "bulb replacement". No tools necessary.
Lift up on the E-brake until the first click. This works for any vehicle (Chevy at least) with daytime running lights.
Look in the fuse box for a fuse marked DT lights
Cheapest returnable answer is to remove the bulbs
Bulbs burned out or fuse and or relay popped
Evidentally the lights were wired up wrong. You will have to take ti to someone and have it streightened out. Are you sure they don't work? They only come on when the engine is running and the vehcile is in gear. If you just start the truck up and look for the lights, they will not be on. It has to be in gear.
Under dash - right side of steering column - attached to crossbar
push your parking brake one click and it will turn them out
