While detailing my Roadster I pulled the bonnet release handle to clean the underside and the windshield wiper arm fell into the gap. The arm must have been broken some time earlier and leaning against the rear edge of the bonnet, so shame on me for not noticing. The last time the car was exposed to rain was in February. The failure was in the cast piece that mounts to the motor armature. It just fractured leaving the stub on the armature. Fortunately the local SC had a replacement in stock.
So this is a warning that you might want to rotate up the plastic cover over the hub to see if there are any cracks forming on your wiper arm.
