My back wiper blade became lose so I took it off from the motor. The whole arm and wiper blade and when I put it back on with the new wiper blade the arm drops down to the back of the hatch and doesn’t wash the window. Is there a way to reset the arm on the motor so it cleans the window and not the body tailgate of the suv? Please help

 

Remove the nut holding tbe wiper and ether looosen or completely remove wiper arm. "Operarate" back wiper, so that the motor naturally stops in the Park position. Align the wiper arm with correct Park position and reattach it.
