• Description:

  Genuine Ford OEM HVAC cabin air intake duct part number HL3Z-19A618-AD, the upper heater case section that channels fresh outside air or recirculated cabin air to the blower motor and downstream evaporator and heater core. This duct fits 17-23 Ford F-150 and 22-23 F-150 Lightning electric pickups across all engine configurations including hybrid. The part supersedes FL3Z-19A618-A and FL3Z-19A618-B from earlier model years, and replaces earlier suffixes HL3Z-19A618-AA, AB, and AC within the HL3Z family. The duct carries integrated foam seals at every mounting surface to maintain a sealed airflow path through the dash assembly. Replacement is required when the original duct cracks, the foam seals deteriorate and cause air leaks, or the recirculation flap mounting point breaks. Symptoms of duct failure include reduced HVAC airflow at the vents, whistling noises from the dash, or air bleeding past closed climate control settings. Installation requires partial dash removal, so plan accordingly. Genuine Ford ducts are dimensioned to match the factory dash openings and seal surfaces exactly, ensuring full HVAC system performance. Ships in original Ford packaging with the standard Ford limited parts warranty.
