During manufacture of the wiper switch assembly in the involved vehicles, certain contacts on the switch terminal could have been manufactured incorrectly. This could lead to a potential short if the wiper is moved from OFF to the MIST setting. A short can cause the windshield wipers to become inoperative.
Owners of the involved vehicles will be notified by first class mail to return their vehicles to a Toyota dealer for replacement of the wiper switch.
