Stumped on wipers

Hyper drive? Ground to the switch. Run an extra lead from the switch to say the door jamb or somewhere you have good ground and try the motor again. More often than not the issue when a motor is in hyperdrive is a bad ground to the switch.

Not parking in the correct position? Check to see where the switch plate/gear housing cover is clocked at. If you have any other problems or continued problem, shoot me an email or pick up the phone...I'd be happy to help you through this.
