good afternoon my name is ***** ***** I will assist

the first thing to do is check the obvious, the bulbs and be sure they are good. check the connectors behind the bulbs for any damage or corrosion. I will attach a wiring diagram foryou to view as you may have a bad headlight switch.


make sure you check all fuses in the diagram with a test light for power
