2013 front windshield wiper motor

[Hjoken]

My wife's yaris front wiper seems to have broken.The arm now freely moves and I can still hear the motor running. I plan to take it apart but assume it is a broken motor/transmission. I plan to take it apart before ordering anything.

I've been trying to look for a replacement but so far only places I see it for sale are the dealer and used on ebay. Even rock auto only offers a rebuild service.
Anyone know why these are so hard to find?

They rarely fail so there's not much aftermarket demand. Take a look at your local self-serve junk yards too.
