1998 Ford Expedition Q&A

1998 Ford Expedition Question: License Plate Lights

Have noticed license plate lights were out. Replaced bulbs, still no lights. Checked fuses, all ok. Tailights are operational. A set of rear back up lights (installed aftermarket) are also not working. Replaced these due to corroded state and still both not working. Replaced relay that comes with fofg light set, still not working. Looking for next item to check. -
Answer 1
I have had the same issue and solved it by cleaning the ground wire. -
