Hello, the vehicle's headlight and the tail light are not functioning. I have checked the fuse , I couldn't see anything wrong with it. Please could you help me with the circuit diagram?

Hi,

The wiring schematics are broken into two sections, headlamps and exterior lighting. The rear tail lamp issue will be under exterior lighting. The headlamp will be under headlamp.

Pics 1, 2, 3, and 4 are for the headlamp. I cut the pic in half to make it more readable. I did, however, overlap them so you can follow it.

Pics 5,6,7 and 8 are the exterior lighting schematics. Again, I cut them in half to make it make them more readable and I overlapped them as well.

I hope this helps. Let me know if you have other questions.

Take care and God Bless,

Does the fog light comes on with the tail light or is there any circuit description for these?

I need to better understand. Where are you testing? Do you see something at the wiring schematics you are using? What colors are the wires? Most grounds will be black.

Let me know.
