I recently replaced my blower motor on my own. Had to unplug the battery (for airbags) and then take apart the under dash /glove box area to get to the blower motor. That required me unplugging the MMI system in order to drop the whole glovebox down. I replugged it all in after and now the MMI system won’t work at all. Screen won’t pop up, usb outlets won’t work. The MMI unit itself has power though as when I hit the eject button it works. Any thoughts on how I can fix this?
