Turn Signal Switch problems of the 2000 Toyota Tacoma

(actual incident date: 01/02/2003 ->message to NHTSA: update your incident date pulldown, 2003 not listed!): on 05/14/2001, turn signal was replaced (courtesy) as precaution from previous driver noted failures. Sometime early spring 2002, driver noticed turn signal malfunction one morning, after that none occured until 01/02/2003 at 10:15am. Driver tried to engage and disengage turn signal multiple times but turn signal failed to operate. Driver had to use hand to signal turning to reach destination. Turn signal malfunction has never occurred with such magnitude as it did with this incident. Approximately an hour later, upon returning to vehicle, turn signal worked fine. Since then no problems yet with turn signal. Approximate mileage of failure: 25,600. In addition, the floor of the passenger side always gets wet/damp when vehicle is washed or when it rains. End note: will bring to dealer to investigate 01/06/2003.
