Replacement Blower Motor Resistor – Reliable HVAC Fan Speed Control Part Numbers Replaced: 8713852010, JA1346, 3A1200, 973459, RU944, 2040020. Please verify your OEM part number before to ensure proper fitment. Compatible Vehicles: Mitsubishi Eclipse (2006–2012) Scion XA, XB (2004–2006) Toyota Echo (2000–2005) Functions and Benefits: Restores proper HVAC fan speed control in heating, ventilation, and air conditioning systems. Resolves issues where the blower fan only works at one speed or stops functioning entirely. Protects other HVAC components, including the blower motor, from potential overload caused by a faulty resistor. Ensures consistent comfort by allowing precise temperature regulation inside your vehicle. Key Attributes: Designed for direct OEM replacement with no modifications required. Built with durable materials to withstand heat and electrical load for longterm performance. Compact size for easy installation in factory location. Tested for reliable operation and consistent fan speed adjustment. Practical Applications: 1. Ideal for drivers experiencing limited fan speed options (for example, only low or speed) caused by a failed resistor. 2. Suitable for restoring full climate control in vehicles with malfunctioning blower performance during seasonal temperature extremes. 3. Effective in systems where intermittent fan operation is disrupting cabin comfort and visibility (defrost function). Ensure compatibility by checking your OEM part number and vehicle model before ordering. This blower motor resistor offers a dependable solution to HVAC speed control problems, helping maintain a comfortable and safe driving environment.
