Does anyone know how to get the rear wiper arm and motor/transmission out of an NX? I can't figure out how to get the arm disconnected from the housing inside the car, and the hole in the hatch is too small to pull either side through. Do I need to disassemble the "transmission" part to pull the arm off? TIA Jon Mistchenko 91 NX2K(RIP) 92 NX2K with broken rear wiper
