replaced bulb and verified fuses were good. High beam worked with old bulb and still worked with new bulb.
Check where the wire harness connects to the headlight assembly. Make sure there is no corrosion.
Also check the wires inside the headlight they can get fried or get disconnected.
I would recommend that you use a multimeter to check the voltage as well. You will need to disconnect the wire from the headlight. Identify the low beam light wires and check if are getting 12 volt..
