Tail light and shift light went out

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Grand Cherokee. If your taillights and gear shift light went out simultaneously, it's likely a fuse issue, particularly if it happened while towing. Check the fuse box for blown fuses related to the tail lights and interior lighting. It's possible that towing put an extra load on the electrical system, causing the fuse to blow. If the fuses look fine, inspect the trailer wiring connector for any damage or loose wires, as a short here can also affect the lights on your Jeep. Replacing the fuse should restore functionality, but it's worth examining the wiring more thoroughly if it blows again. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
