UConnect stopped working

There is most likely a fuse, i don't have a Cherokee manual handy for that model year but i know on the Liberty of the same year there is a fuse for the UConnect in the interior fuse box. If you have your manual in the glove box check the glossary for fuses and there is a diagram showing what each fuse is with a number and an explanation of what each fuse runs in a chart. If the fuse is ok it might just need to be reset, pulling the battery negative cable and waiting 10-15 mins and then reconnect will usually clear up any issues and reboot everything, just be aware that if you have antitheft lock on the stereo that you disable that before pulling the battery cable otherwise the radio will be locked after reconnecting the battery cable. You can also try just pulling the fuse that supplies power to the Uconnect and leave that out for a bit.

However, i kinda doubt its a fuse, because usually the Uconnect and stereo are on the same fuse, so if everything else is working that might not be it but its worth checking before taking it to a dealership.
