NO TAIL LIGHTS 05 Town Car

[WinkinLincoln]

HELP!!, I could use your council, advice and suggestions regarding my 05 Town Car tail lights NOT WORKING when my headlights are turned on..
Fuses checked no problem there.. Has anyone else dealt with this problem and if so, the much needed solution? Also my rear window defroster stopped working.. fuses all working..
Thanks everyone..

Does the brake and turn signal lights work?

If yes, the ground is good as it is shared.

Action.
