Hello,

Since none of the lights are functional it can be due to a faulty light switch.
A malfunctioning switch will not turn on the lights.
It the headlight switch located on the left of the steering wheel.
This switch can be tested using a multimeter by reading the internal resistance.
I have included the testing procedure for the switch (look below).

Another possibility is that the integrated power module is faulty. That module located under the hood next to the fuse block (see diagram below). It controls many of the light functions. Fairly common issue with these years of vehicles.


I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
