hey man, generally those sockets stay pretty legit for a long time without problems , it is a very good possibility its just a blown a fuse, is there anything else not working in the car right now? im not exactly sure whats on the same circuit as that in our ep3s but check all your interior stuff (radio, flashers, gauge cluster etc...) if any of them are out as well its most likely a fuse, or you can just check the fuse and skip the checking of other components
