Dirty Port

Dirt, dust, and other small debris may enter the Jeep’s USB port. These small objects may interfere with the connection between the vehicle and the connected device.

Blown Fuse

USB ports in vehicles, including Jeeps, often have fuses to prevent harm if electronic issues occur. It’s a component that generally sacrifices itself instead of the USB port or the attached device.

Some of the relatively common causes of blown fuses in vehicles are:

  • Frayed wires
  • A system conductor exposed to harsh weather
  • Short circuit from connecting a faulty device
  • Incorrect fuse used
  • Improper fuse installation

Software Error

The firmware of the Jeep’s USB port might encounter a glitch, preventing the terminal from working correctly or at all. This event may happen because of different reasons, including an error from an update or the vehicle is using outdated firmware.

Bad Cable

Perhaps it’s not the USB port that’s at fault but the cable used for the smartphone connection. Troubleshoot this concern by changing the cable. Then, inspect if the new cable allows you to use the smartphone and/or Jeep’s features through the USB terminal.

Faulty Port

If your Jeep’s USB port is still unresponsive after using extensive troubleshooting techniques, the terminal might need replacing. You may use a DIY solution to replace the port. Otherwise, consult the Jeep’s manufacturer or a trustworthy car repair technician for professional automotive assistance.

Unlike the other possible solutions already mentioned in this post, replacing a faulty USB port in a Jeep often requires sufficient confidence and automotive skill. If you aren't sure you're up to the task, request help from professional automotive technicians.

Some of the steps in this section may differ depending on your Jeep’s model. Nonetheless, here’s the general procedure on how to replace a faulty USB port in a Jeep:

What You’ll Need

  • Flathead screwdriver
  • Panel remover
  • Socket and ratchet set
  • Replacement USB port

Step-By-Step Guide

Step #1: Remove The Center Console

Start removing the center console by moving the front seats forward. Then, move the rear seats backward as far as possible. Bend down to the height of the center console and look for a plastic cover.

Use a flathead screwdriver or panel remover to take out the small opening on the plastic cover. You should be able to expose a large bolt that you need to unscrew using the appropriate socket. Once removed, repeat this part of the procedure for the other side of the plastic cover.

Next, unscrew the plastic cup holders and remove them. Then, use the flathead screwdriver or panel remover again to remove the gear shifter’s cover. Disconnect the shift lever’s wire afterward.

Move forward by removing the driver’s side footwell. You might be able to pull it out using your fingers. Otherwise, use the flathead screwdriver or panel remover.

At this point, you should be able to see tabs that are securing the center console in place. Push those tabs with a tool and remove the center console.

Step #2: Remove The Bad USB Port

Go to the passenger side’s footwell. Since you removed the center console, you should have a clear view of the assembly encasing the USB port. Remove that assembly by removing the upper and lower bolts located on both the driver and passenger sides.

Unclip the assembly from its sides afterward. Once it’s loose, you can pull it out of its mounting bracket slowly. Disconnect and remove the bad USB port from the vehicle afterward.

Step #3: Install The New USB Port

Install the new USB port into the same location as the offending unit. Connect it with the appropriate wire.

Next, return the USB port assembly into place and ensure the clips latch. Secure this assembly by returning the bolts you removed earlier.

Go through the steps in this section in reverse order to return the center console and the other components to their original locations. Don't forget to slide the front and rear seats back in place.

Once you return everything, turn on the Jeep’s engine. Then, check if the new USB port is working as expected.

Note: You may need to replace the wire connecting the USB port to the Jeep if you see issues like cuts or frays on it.
