I installed a new bulb but no results. I changed the dimmer switch about a month ago, that's when i noticed the light didn't work at all. Please help me out. Thanks

I would use a test light and test the light blue/green wire for power at the cluster when the high beams are activated. Here is a guide that will help, and I have found the headlight wiring diagrams so you can see how the system works.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
