Pull the headlight out and test at the connector with a multimeter or test light.
Here is the pinout...notice that this is the headlight side, so reverse left to right for the car side connector:
If you're not getting power at the connector and the fuses are good, it is likely the headlight switch. They can be revived by spraying electrical contact cleaner
inside the switch (spraying down the shaft will get some inside) and turning the switch back and forth. The contact inside can get carbon build up that creates too much resistance.
If the cleaner doesn't help, you may need a new switch.
