My rear wiper stopped returning to the cradle properly. It has not been bent or modified in any way. Normally when it is shut off it kicks out a little as it goes under the window to make it seat in the cradle properly. The other day it just stopped doing that. Now it hits the cradle and gets stuck. If I pull it out manually it will then lower the last 1/2 inch or so into the cradle. Otherwise it stays stuck and I won't turn back on via the switch until I un-stick it.

I did remove it and spray it down with white lithium grease and clean it up and replace it on the vehicle. This did not help at all. I don't see anything physically broken, loose, or missing.

Does anyone know how to fix this?
