Universal Air SW11227C HVAC Blower Motor Resistor

Universal Air Blower Resistor SW11227C

Universal Air SW11227C is an HVAC blower motor resistor for vehicles with manual A/C controls. It is used to regulate blower motor speed in the cabin HVAC system, helping restore proper fan operation when lower speeds stop working or the blower output becomes inconsistent.

Key Features

• HVAC blower motor resistor for manual A/C control systems
• Direct-fit application coverage for select Dodge, Jeep, and Ram models
• Supports blower motor speed control in the heating and air conditioning system
• Fits 2003-2006 Dodge Viper, with Manual A/C Controls; Blower Resistor
• Fits 2008-2010 Dodge Viper, with Manual A/C Controls; Blower Resistor

• Fits 2001-2004 Jeep Grand Cherokee, with Manual A/C Controls; Blower Resistor
• Fits 2000-2001 Dodge Ramcharger, Blower Resistor

Detailed Description

This blower resistor is built for HVAC systems that use manual fan-speed control, making it a direct service part for Dodge Viper, Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, Jeep Grand Cherokee, and Dodge Ramcharger applications. The SW11227C part number is useful when replacing a failed resistor that causes limited fan speeds or no blower response at certain settings. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Blower motor works on only one speed
• Lower fan speeds stop operating
• Intermittent cabin airflow from the vents
• No response from the HVAC fan switch at selected settings
• Uneven heating or cooling output in manual A/C systems

Installation Notes and Tips

Verify the vehicle uses manual A/C controls before ordering. Match the original connector and mounting style to the existing resistor, and inspect the blower motor and related wiring for heat damage before installation. Confirm fitment by year, make, model, and HVAC control type; SW11227C is listed for the applications shown above.
