2011 Gen 3 Prius - Front Windshield motor grinding sound

Hello

This weekend had my first road trip, part of the trip had on and off rain where I used my wipers a lot. The next day when trying to use my wipers, you could hear the motor from inside of the car. Sounds like a gear grinding sound.

Getting it checked tomorrow, hope it doesn't cost much.

Funny thing, we could not hear the grinding sound at HWY speeds, either the road noise covered the sound or it was working fine at those speeds. Interesting to see what will be the result of this.


Thanks
