: Receives a Pulse Width Modulated (PWM) signal from the HVAC control head. Voltage here varies based on the fan speed setting (e.g., ~1.6V on low to ~6.1V on high).

: Systems using a resistor pack typically feature four speeds. The resistors are positioned in the air stream to prevent overheating; if only high speed works, the resistor pack is likely failed. Common Failure Points in the Diagram Freightliner M2 Blower Motor Wiring Diagram
