Windshield Wiper/washer Switch problems of the 1998 Chevrolet C/k Pickups

Windshield wipers will stop working creating a very dangerous situation.

Windshield wipers are not functioning correctly. Fortunately the wipers are functional although they will not function intermittently. They also do not park when the switch is turned to off position and will continue to operate until they park in random positions at a random interval up to five minutes observed so far. The "mist" operation also exhibits the same behavior and but be used to eventually get them to stop in an acceptable position for driving. Internet research indicates this is a common problem for vehicles of similar type for several years previous (for which there is a recall) and is related to a connection to the circuit board that controlls wiper operation.
