THE IGNITION SWITCH COULD EXPERIENCE AN INTERNAL SHORT CIRCUIT.
THE NUTS WHICH HOLD WINDSHIELD WIPER MOTOR TO THE WIPER MODULE MAY NOT HAVE BEEN SUFFICIENTLY TIGHTENED AND MAY LOOSEN OR COME OFF. THIS CAUSES CHANGED WIPER PATTERNS, OR THE WIPERS MAY JAM IF TWO OF THE THREE NUTS COME OFF.
THE PARK ROD ASSEMBLY CONTAINS A PARK CAM WITH INADEQUATE SURFACE HARDNESS, WHICH COULD LEAD TO PARK DISENGAGEMENT OR NO PARK ENGAGEMENT WHEN THE LEVER IS PLACED IN PARK.
