Here is part of the TSB that concerns that. The TSB is 05-4-9. So if there is no problem found there, replace the multi-function switch.

ISSUE:
Some 2003 Crown Victoria/Grand Marquis vehicles may exhibit the windshield wiper turning on intermittently without activating the wiper switch.

ACTION:
Inspect the wiper motor and connector for signs of corrosion and/or moisture. If any corrosion or moisture are found, and the wipers exhibit an intermittent uncommanded operation, replace the wiper motor and connector/pig tail. If no visible sign of moisture or corrosion is present follow normal diagnostics in Section 501-16 of the Workshop Manual.
