Have you disconnected the battery recently?
You won't find a blown fuse because the main beam and low beam work on the same fuse. If the car has lost power or somehow the power source has been disconnected, the body control module needs to be reset by Ford.
So, is the low beam working in only one headlight?
Have you tried swapping the left and right bulbs for the low beam?
Do you have power at the connector for the bulb that is not working? Have you tested it with a multimeter?
Do you have a main headlight connector or do you have seperate harnesses for each bulb?
The 3 wires are low beam, high beam and ground. So you should have power at one of the 3 wires when you switch to low beam and then you will have power at the 2nd wire when you switch to high beam and the 3rd is ground. You need to check if you have power at the correct pin for the low beam, on both sides.
Happy to help :) Thank you for using JA.
All the best!
Yes it most likely needs a reset.
Glad I could help. All the best and thank you for using JA!
