3 speed wiper motor

I wouldn't force it. There is a plastic gear and other plastic Park switch mechanisms in there. There are pictures in the FSM. Have a look.
I tried to take it apart and pull the motor out to see if I could turn the motor by hand with all the mechanism off the shaft but one of the screws is stuck. I soaked it in kroil and will try again tomorrow. I'm about will to bet its locked up too. I looked in the fsa I couldn't find it I will look again.
