How You Fix UConnect Touch Screen?
Now that I’ve ascertained the possible causes, let’s look at how we can fix these problems.
The first port of call is to do a soft reset. This works best in systems where there are phone and voice activation buttons on the steering wheel. Here is how you do the reset:
- Press the phone and voice activation buttons for 10 to 20 seconds.
- Your UConnect will show your Jeep trim logo and switch off
- Your screen will switch on again showing your trim logo
- Your UConnect system is now reset
Test the touch screen to see if it’s now working. If not, try the following method.

Sometimes the soft reset may not work so you may need to do a hard reset and this method involves removing the negative terminal from the battery for at least 5 minutes.
Doing this allows all the stored charges in the system to completely discharge. Here is how this works.
- Remove the negative or both terminals from the battery.
- Wait for at least 5 minutes
- Reconnect the terminals
- Turn ignition to ON position
- Your UConnect System will reset
When you try the above methods and the problem persists, you may need to try a firmware upgrade to see if that takes care of the problem.
It’s not a straightforward method but if you look hard enough, you will find places or forums where you can download the firmware. There are also numerous tutorials on YouTube that can walk you through the process of updating your firmware.
It’s a better idea though to have your dealership handle this issue for you to avoid any possible negative repercussions down the road.
Replacing the Screen
The last port of call is to consider that your screen is faulty and needs replacement. In this case, you will need to have the touch screen replaced. Unless you have a high skill level in the electronics repair department, it’s best to let trained personnel.
