Product Details
Is Your Heater or AC Fan Acting Up?
If your vehicle's blower fan only works on high speed, or if certain fan speeds don't work at all, the problem is almost always a failed blower motor resistor—specifically the manual control module version.
This essential component controls the voltage flowing to your blower motor, allowing you to adjust fan speed from low to high. When it fails, you lose that control, leaving you with limited or no airflow.
What Is a Manual Control Module Blower Motor Resistor?
Unlike digital climate control systems, manual HVAC systems use a resistor module to regulate fan speed. When you turn the fan knob, the resistor limits electrical current to achieve different speeds. Over time, heat buildup and constant use can cause the resistor to burn out—especially in vehicles where it's mounted directly in the air stream.
