cigarette lighter stopped working

Hi all. My cigarette lighter socket has always been hot without the ignition on. That’s the way it was factory installed. For some reason, it has stopped getting power. I traced and tested the wires (about a foot long) from the socket back as far as they would go to the major harness where it gets lost among all the other wrapped wires. I checked the fuses and they’re good. Why am I not getting power to the socket anymore? This is on an ’04 Outlander 400 Max XT. In the meantime, I’ve connected the socket directly to the battery with a 2 amp inline fuse. I use the socket to power my gps. I’d still rather keep using the original wires if possible….it’s cleaner. Any thoughts/ideas? Thanks.
