Left And Right Headlights Not working

Vehicle is 2004 Chevrolet Impala.

Problem is left and right headlamps nt working,but all other lights functioning right.

Troubleshooting details:----

First confirm the headlamp controlling fuses are not blown.
Next check the headlamps,are they blown or are they powering up right if you try them connecting anywhere else.
If both bulbs and fuse checked ok,

Then the issue can be with faulty headlight controlling relay.
These relay is located in the left side dash junction box.It will be on the driver side end with the door open.Also there will be the Access panel to be removed.Once the panel is dismounted,the internal fuse box diagram will be seen.It will give accurate info of which fuse and which relay is for what purpose.

These details will help
Thanks

Plymouth Colt Vista Head Light Wiring Diagram?

The Headlights are used for nighttime illumination, these sealed beams have one or two tungsten filaments in a sealed glass case. Lights with two filaments can be used for both high and low beams, but lights with one filament are only used for high beams.Halogen lights, used in late model vehicles, emit more light than a standard sealed beam. Identifiable by the word "halogen" on their face, they're easy to replace and relatively inexpensive.They can also be used as aerodynamic lights that have a small halogen inner bulb that's replaced without removing or replacing the headlight assembly.
