My 2011 Jeep Patriot started having issues with the radio head unit a few months ago. The radio started occassionally cutting out and coming back on a few seconds later. The issue got progressively worse until it was happening almost continuously. I took the head unit out of the dash and inspected the wiring and found no issues. I unplugged the wiring harness from the head unit and plugged it back in and the radio started working again (like magic). I put the whole thing back together and it worked fine for a few day - then the flickering issue started up again. I repeated the process and got it working for another week or so before the flickering began again.
Any ideas of what the issue may be for things I should be checking for? I thought the head unit may be going bad but the fact that it starts working fine again after unplugging/replugging it in make me doubt that diagnosis now.
