how do i fix my daytime running lights on my 2001 grand prix gt headlights work perfect
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.
Taillights and daytime running lights not working may be caused by a blown fuse. The fuse can be found in the fuse box in the engine compartment.
The daytime running lights work of the high beam, check those first.
yes
The first thing I'd do is check the fuse. If the fuse is good the you might have a short in a wire somewhere.
The daytime running lights are the low beam lights run by a specific circuit. If they don't work then check your fuses and then the wiring harness for damage.
Sounds like it might be a bad ground
If the headlight that runs through the modulator first is out then the daytime running lights won't work. Change the bulb and the daytime lights should then work.
Look in the fuse box for a fuse marked DT lights
Check fuses, breakers and relay in power distribution box
