Passenger headlight out. 2019 ranger xlt.

[wayne1397]

Driver side headlight works and swapped out the bulbs. Bulbs are good. Checked fuses under the dash and the switch. Hoping someone has had a similar problem or can give some advice on what to look for next.

Are all lights out on the passenger headlight assembly or just the headlights (Low and High) beams and is this a LED or Halogen assembly.

Here is the wiring diagram for the right side headlight. Check ground G122 for a good connection. Check connector C1041 at the headlight. Also check for any DTCs with a code scanner.

Halogen original from factory. The marker light works(yellow). Just the high beam and low beam doesn't work. Have a hand held code reader but no codes come up for the headlights. Just a faulty knock sensor code shows for bank 1 and bank 2

You may want to use Forscan and an adapter to read any DTC codes. Many inexpensive code readers only read powertrain codes.

Thks. Found a broke ground wire. Hopefully this will fix it. Started to repair but had dead battery.

Good find - G123 is for the Low / High Beams
