What is the situation when the rear charging port of Jetour X90 has no power?
4 Answers
There are two situations when the rear charging port of Jetour X90 has no power: connecting the phone through the USB port, but the phone shows no charging display; connecting the phone through the USB port, the phone shows a charging display, but it just doesn't charge. No charging display on the phone: The vehicle USB port fuse is blown (find the corresponding fuse through the vehicle manual, and replace the spare fuse in time if there is a blown phenomenon). The phone charging port spring is loose, causing poor contact. The phone shows a charging display, but it doesn't charge: If this happens, it means that the USB port is only for reading U disk data, not for charging the phone. You can check the application range of the USB port through the vehicle manual.
I've seen quite a few automotive electrical issues, and there are several reasons why the rear charging port of the Jetour X90 might not have power. The main causes include a blown fuse, poor wiring contact, or a faulty USB port itself. The fuse is the most common culprit, especially the independent fuse for the rear row. Prolonged use of high-power devices can cause it to blow. You can check the fuse labeled "USB" in the fuse box on the driver's side. As for the wiring, if the car experiences a lot of bumps, the rear wiring may become loose or break, leading to a short circuit. The USB port can also develop poor contact if it gets wet or is plugged in too forcefully. A simple self-check method: use a multimeter to measure the voltage at the output end or try charging another device to see if it works. Once confirmed, replace the fuse or send it for repair promptly to avoid bigger problems caused by a short circuit. In daily use, avoid letting heavy objects press on the rear wiring.
My Jetour had the same issue before - the rear USB suddenly stopped working, and my friend couldn't charge his phone. I fixed it myself by checking the manual for the fuse location, found the blown fuse for the rear USB in the compartment under the steering wheel, and replaced it - everything worked fine afterwards. If the fuse is intact, you should check the USB port for dust or damage, try unplugging and replugging the cable, or see if the wiring connections have come loose from prolonged vehicle vibration. I recommend keeping a small voltage tester handy, or testing the front USB ports first. During maintenance, remind the technician to inspect the rear circuit to avoid travel inconveniences.
Be cautious when the rear charging port has no power. Common causes include a blown fuse, wiring issues, or a faulty port. I recommend checking the fuse box first to locate and replace the relevant rear fuse. If the issue persists, avoid tampering further, as a short circuit could damage the vehicle or pose risks. Contact a professional repair shop to inspect and ensure the cables are intact. For prevention, avoid placing damp items in the rear.
