The defect

VEHICLE DESCRIPTION: CERTAIN HEAVY DUTY TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 103, "WINDSHIELD DEFROSTING AND DEFOGGING SYSTEMS." THE MODE DOOR IN AN HVAC SYSTEM CAN BECOME INOPERABLE. THE MODE DOOR CAM AND ACTUATOR COULD BIND, CAUSING THE CAM RETAINING TABS TO SHEAR OFF.

The risk

THIS FAILURE MAY INHIBIT THE ABILITY TO DIRECT AIR BLOWING FROM THE HVAC SYSTEM TO THE WINDSHIELD, POTENTIALLY REDUCING THE DRIVER'S VISIBILITY.
