When the windshield wiper switch is turned to INT

When the windshield wiper switch is turned OFF

When the windshield wiper switch is turned to MIST

Are all data list values correct?

YES

The FR WIPER MIST SW to FR WIPER HI&LO SW, FR WIPER HI&LO SW to FR WIPER INT&LO SW, and FR WIPER MIST SW to FR WIPER INT&LO SW wires are OK. Intermittent failure, the system is OK at this time. Check for loose or poor connections.
