The Alltrux ATX942-1164 Blower Resistor replaces OEM BOA91592 and is designed as a service replacement for heavy-duty truck HVAC blower motor control systems. It regulates blower motor speed by controlling electrical resistance, allowing multiple fan speed settings and supporting consistent cabin airflow and climate control performance in fleet and vocational environments.

Blower resistors play a critical role in HVAC operation by managing voltage supplied to the blower motor to produce different fan speeds. As original resistors wear, overheat, or fail electrically, blower motors may only operate on one speed or stop functioning entirely. Replacing worn blower resistors helps restore proper fan speed control, improve HVAC performance, and reduce unplanned service events.
