I just fixed mine , I had to unfasten rod connected to wiper motor. the part that joined the connecting rod to motor was in wrong position. I removed one lone screw .wiggled this piece off wiper motor, and turned wiper motor by hand to the right position my blades were trying to go down from start position and not up.so I turned motor to the opposite position 180 degrees. blades started and stopped in right position
