Universal Air Conditioner SW11257C HVAC Blower Motor Resistor

The Universal Air Conditioner SW11257C is an HVAC blower motor resistor, also called a blower resistor or blower motor speed control resistor. It controls the speed of the heater and A/C blower motor, so you can set the fan speed you want for cabin comfort.

Key Features:

• HVAC blower motor resistor for regulating blower fan speed
• Replacement part for restoring blower speed control
• Helps maintain the desired temperature inside the cabin

A failed blower resistor often shows up as a blower that works only on certain speeds, such as high only, or not at all. Replacing it restores normal fan speed control.
