The Alltrux ATX942-1036 Blower Resistor / LPM Module replaces OEM 85120287 and is designed as a service replacement for heavy-duty truck HVAC blower motor control systems. This resistor module regulates blower motor speed and electrical load management, supporting consistent cabin airflow and reliable climate control performance in fleet and vocational environments.

Blower resistor or LPM (Load Power Module) units play a critical role in HVAC operation by controlling voltage supplied to the blower motor to produce multiple fan speeds and maintain proper electrical system balance. As original resistor modules wear, overheat, or fail electrically, blower motors may operate intermittently, only on high speed, or stop functioning entirely. Replacing worn blower resistor modules helps restore proper fan speed control, improve HVAC performance, and reduce unplanned service events.
