The wipers were multi controlled with slow to two speed(slow and faster) steady. Then we had the wipers not working with control. It was either on or off. Then it got to sounding like the motor was grinding as the wipers moved slowly. They finally have stopped completely. I can turn the control on and hear a clicking noise at the fast and slow spots. I tried to physically move them with the control on. They will not move. I have not attempted a repair as of yet. I want to see an example of how to get to the wiper motor.
