73 dart headlight issues

Would this issue be related to my heater and windshield wipers not working?
It shouldn't be but with the little info so far, yes its possible.
It shouldn't be because the heater fan and wipers only get power when the key is in run or accessory position.

Headlight circuit is wired as shown (Details such wire colors and particular connector cavity sometimes differ from year to year)

The headlight's power goes into the B1 terminal on the switch. Headlights have a circuit breaker in the switch.
Parking lights get power from the B2 connection on the headlight switch. B2 is fed from a fuse that is always hot.
Wiper switch usually has circuit breaker and gets power from the switched 'accessory' feed.
Heater fan gets power from a fuse that gets power from the switched 'accessory' feed.
