Reset the wiper arm. At the bulkhead end of the arm is a big nut on a tapered shaft. (might be under a cover). Slacken the nut and loosen the arm from the tapered shaft. Move the wiper to a different position on the windshield and tighten the nut. Test wiper to see that blade returns to the new position.
Broken linkage? Disconeccted linkage? EDIT::: The most likely cause is a bad wiper control module, its attached to the wiper motor
Replace the wiper motor with a NEW one (do not use a rebuilt!)
It is definitely a pin inside the wiper motor that is worn out. I just had mine replaced in my 02 Montana. The pin can be seen by removing the cover from the motor.
There is no "reset" in the wiper motor. If your wipers do not park, it is likely your wiper motor parking contact or cam is broken. Try running the wipers with the key in the "ON" position, then turn the wipers off using their switch while they are up on the windshield. They should park themselves at the bottom. The good news is a wiper motor is pretty cheap at a junkyard, and not too hard to replace.
