Detailed Description

Dorman 973-086 is an HVAC blower motor resistor engineered for select Kia Sedona, Rio, Spectra, and Sephia applications. It is used to regulate blower motor speed so the cabin system can deliver the correct airflow for defrost, heat, and air conditioning settings. This part number is a practical OE-style replacement for vehicles experiencing loss of one or more fan speeds, intermittent blower operation, or no blower output at all. Fits 2005-2006 Kia Sedona, 2001-2005 Kia Rio, 2002-2004 Kia Sedona, 2004 Kia Spectra, 2000-2003 Kia Spectra, and 1994-2001 Kia Sephia.

What It Helps Fix

• No blower motor operation at selected fan speeds
• Only one fan speed working in the HVAC system
• Intermittent cabin airflow from the heater or A/C vents
• Loss of proper defrost, heat, or cooling control
• Burnt or heat-damaged original blower resistor

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This resistor uses a rectangular female connector with blade terminals and mounts with two bolt holes. No wiring harness or mounting hardware is included, so reuse the original hardware where applicable. Confirm whether your Kia Sedona, Rio, Spectra, or Sephia has the listed HVAC configuration before ordering, including the note for 2005-2006 Sedona models with automatic air conditioning controls and the 2004 Spectra models without air conditioning.

Quality Assurance

Dorman designs replacement parts to match original equipment fit and function on specific vehicle applications. Dorman 973-086 is built as a direct replacement for supported Kia HVAC systems and includes instructions for installation guidance.
