Craig replies: If the wipers operate through the normal range but park in  
the middle, it's a failure of the parking cam-contact in the wiper motor (or,  
remotely possible, the relay.  If the wiper's arc is out of whack (running  off 
the end of the glass), and they're both the same, look to the motor output  
lever.  If only one of the wipers is out of whack, look to that mounting  
spline for that wiper.
