04 f-150 rear lights
I also forgot to mention that all other lights work as well as the right rear running lights. I do have power going into bulb socket. It's not the socket cause I tried it on the left rear and it worked fine
it is Chassis Ground...start with a Fresh battery...04 is Kaput, by now...make sure there is plenty of Amperage....clean the bolted connection to the frame...and the second to the engine free of corrosion....perhaps with a wirebrush, rag and a little brake cleaner...you need Good ground~
