What's the issue with the touchscreen on my Jeep Wrangler not functioning?

There are various reasons why the touch screen in a Jeep Wrangler could stop working. To assist with troubleshooting, it is important to pinpoint the specific way in which the touch screen is malfunctioning. For example, is it still showing a display but not responding to touch inputs? Is it displaying an all black or all blue screen? Each of these scenarios points to a common issue. A completely black screen typically indicates a wiring problem, where the touch screen/head unit is not receiving power to function. A blue screen suggests a software failure, which usually requires taking the vehicle to a dealership for reprogramming. An unresponsive touchscreen is usually due to damage to the digitizer underneath. If you inspect the screen closely, you might identify a point of impact causing the damage, but unfortunately, this often means the touchscreen will need to be replaced.
