(888) 312-8812 Login SignupCab comfort depends on more than a working fan—it needs adjustable control that actually responds to input. The Peterbilt HVAC Blower Motor Resistor provides that responsiveness in sleeper cabs, where ventilation isn’t just background but part of the working experience. When airflow settings stop shifting, this part is often the quiet fix that restores functionality without fan replacement. This resistor adjusts voltage levels to allow fan speeds to change appropriately, avoiding abrupt airflow patterns or stagnant cabin air. Get the Peterbilt E9773 today.
