DZ97189585302 SHACMAN Blend Door Actuator Motor The DZ97189585302 is the blend door actuator motor for SHACMAN trucks. It drives the air mix damper inside the heater and AC box, so the cab warms or cools the way the driver sets it. When the old motor gives up, the door sticks and the vents blow one temperature only; this unit puts that control back.
