ABSTRACT:
A vehicle window wiper system has wipers 12 with a range of motion between an in-wipe position I and an out-wipe position O when the wiper system is in a run mode, and a variable park range for the wipers between the in-wipe position I and a depressed park position P when the system is in a park mode. The wiper system has a reversible motor 40 for rotating a shaft 42 in a first direction when in the run mode and through a first predetermined arc in a counter direction when in the park mode. A clutch mechanism 38 mechanically connected with the shaft 42 has a lock pin 64 which operates to prevent reverse rotation of the clutch mechanism 38 when in the run mode and to secure the clutch mechanism 38 in a predetermined position when in the park mode. The lock pin 64 also stabilizes the clutch mechanism 38 when the wiper system is transitioning from the park mode to the run mode.
