Hello,

There are 10 fuses that run the headlight system through the main body ECU (BCM). Here is a guide to help check the fuses and the headlight wiring diagrams so you can see how the system works and what fuses to check:

If all fuses are good I have included how to replace the BCM. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
