Hello all!
I’m in need of some help. My 8.4 Uconnect screen is not working at all. If I push the voice command buttons on the wheel, it seems like I can use the phone, but that’s it. Just a blank screen.

I’ve tried unplugging and replugging the battery. No luck. I check the fuses. Both the screen fuse and the radio fuse are fine. I know my battery is on its last legs, but nothing else is acting up.

I’d like to avoid going to the dealer because they’re so expensive lol does anyone know of anything else I can check or try?

Thanks all!

You have checked all the usual items. I would get the new main battery. Probably will not help with the Uconnect but battery issues can cause the electronics to act weird. If you have a OBD2/CAN scanner that can read all codes (not just powertrain codes) you can plug it into the car's OBD2 port and see if any diagnostic codes have been logged (e.g. U0147-00, Lost Communication with Telematics Gateway).
