Rear wiper on my 2011 3.2 AWD cracked where it connects to the motor shaft, so the shaft just spun and the arm ended up in weird positions. Tried removing the arm but the nut was rusted solid…I ended up damaging the motor trying to remove the nut.

Long story/ short; ordered a new motor and arm from FCP Euro. Discovered the new arm is a replacement for the now discontinued original arm and needs a different wiper blade. So if you buy the new arm (pictured) you have to order the matching blade, part #30747762. Third pic below illustrates the new arm and old blade incompatibility.

Hope that helps someone out there…

p.s.: the wiper motor from FCP appears to be exactly the same as the OEM unit. It’s a Magneti Marelli part…Nice piece. New one on the bottom, old one on top in the last two photos.
