A wiper system has some interesting design elements. There's a "park switch" in the wiper motor that senses when the wipers are in the park position. When you turn the wiper switch off, the "park switch" keeps the wiper motor running until the wipers are in the park position, then the "park switch" shuts off the wiper motor.

For continuous operation, the wiper switch applies power to either a low speed winding in the wiper motor or a high speed winding.

The intermittence of the windshield wiper is controlled by the TIPM.

If you are having trouble parking the wipers I would suggest checking the park switch in the wiper motor.
