Are you experiencing issues with your 2011-2020 Jeep Grand Cherokee’s Uconnect system? Is the screen blank and not responding? Don’t worry, we’ve got you covered. In this article, we will guide you step by step on how to locate the battery in your Jeep Grand Cherokee and fix the Uconnect screen issue.

Key Points:

  • Locating the battery in a 2011-2020 Jeep Grand Cherokee.
  • Accessing the battery under the passenger seat.
  • Disconnecting the negative terminal.
  • Removing the secondary battery for a complete power reset.
  • Reconnecting the battery and checking if the Uconnect system is back to normal.

Let’s dive into the detailed process and get your Uconnect system up and running again.

Step 1: Locating the Battery

Unlike most vehicles where the battery is found under the hood, in a Jeep Grand Cherokee, the battery is not located there. To find the battery, begin by opening the passenger side door. Then, move the passenger seat all the way back to the stops. Underneath the seat, there is a plastic piece. Lift it up to reveal the battery.

Step 2: Removing the Battery Cover

Now that you’ve located the battery, you need to remove the plastic cover for better access. Move the passenger seat all the way forward to create space. Go to the back of the Jeep and find the plastic piece mentioned earlier. Start lifting it until it comes out easily. Move the plastic cover aside, and you’ll see the battery right underneath.

Step 3: Troubleshooting the Uconnect System Issue

The reason why we accessed the battery is because the Uconnect system is lagging or not responding. This issue often occurs after a battery jump-start. To fix it, follow the next steps carefully.

  • Start by disconnecting the negative terminal on the battery using a 10mm wrench. This may not solve the issue immediately.
  • There might be a secondary battery in the Jeep Grand Cherokee, responsible for powering the Uconnect system. To make sure this secondary battery is also disconnected, remove the 13mm terminal connected to it.
  • Once you disconnect the secondary battery, all the lights in your Jeep should turn off. This indicates that there is no power left in the system.
  • Leave both batteries disconnected for about a minute to ensure a complete power reset.

Step 4: Restoring Power and Checking if Uconnect is Back

After the power reset, it’s time to reconnect the batteries and check if the Uconnect system is back to normal.

  • Start by reconnecting the 13mm terminal and secure it properly. Then, reconnect the negative terminal on the main battery using the 10mm wrench.
  • Once both batteries are reconnected, it’s time to jump inside your Jeep and start the engine.
  • If the Uconnect system powers on and functions properly, congratulations! You’ve successfully fixed the issue. Enjoy your seamless navigation, phone connectivity, and entertainment system.
