Control cab airflow routing with the Peterbilt HVAC Mode Cylinder Vane. This internal HVAC component directs conditioned air within the climate control housing based on driver-selected vent positions. It functions as part of the mode door assembly, guiding airflow toward the defrost, panel, or floor ducts without restricting volume. Molded polymer construction is formed to withstand repeated temperature fluctuations from heater core and evaporator operation. Proper installation of the Peterbilt S31-6016 HVAC mode cylinder vane restores accurate airflow distribution within the cab ventilation system.
