You may have reinstalled the wiper motor crank arm in the wrong position. You can try the following: 1) Remove the wiper motor crank arm from the wiper motor. 2) Turn the key on with the engine off. 3) Set the wipers to pulse - the wiper motor should start moving. 4) When the wiper motor stops turn the ignition off - the wiper motor will be in the intermittent rest position. 5) Carefully reinstall the crank arm with out turning the wiper motor shaft. The crank arm is properly aligned when there is a 4-8 mm gap between the v-grove link on the crank arm and the raised tab on the wiper motor mounting plate. 6) with the crank arm in the correct position tighten the crank arm screw. If the wipers still do not park correctly recheck the crank arm alignment, if it OK you may need a new wiper crank arm or the tab on the mounting plate has been damaged.

I had the same problem with my wiper motor. It' a corrosion problem that I solved using WD-40 or Jig-a-loo. Start the wipers and shoot WD-40 on the gears (on the left under the hood) while it's working. Don't be affraid to shoot a lot and let it work a few minutes. Then turn off the whipers and it should be OK. You may have to do this a few times but believe me it really works.
