2003 Honda Civic Windshield Wipers

My wipers will stop, there is not problem with them going on and off randomly or "by themselves", the problem with them is parking.

They stop anywhere on my windshield, and unless I time it to stop at the bottom, they usually wont.

What could be my problem here?

The car is a 2003 Honda Civic EX, is it the complete motor, a relay switch, or what?

thanks!
