Compatible Vehicle: Dodge Dart (2013 model year) Product Overview: This blower motor resistor is designed to restore proper operation to your vehicle's heating, ventilation, and air conditioning (HVAC) fan system. If your heater fan or air conditioner blower only works at certain speeds, or is stuck on or low, a failed blower motor resistor is often the cause. Replacing this part can quickly your fan speed control to normal, ensuring comfortable cabin temperatures and preventing additional wear on your HVAC components. Key Benefits: Restores full fan speed control for HVAC systems Helps maintain precise temperature regulation inside the vehicle Prevents further damage to the blower motor and related parts Direct OEM replacement for fit and performance on compatible models Features: OEMquality construction for durability and reliable performance Exact replacement for specified part numbers, ensuring hassle installation Designed specifically for 2013 Dodge Dart for compatibility Engineered to meet or exceed original manufacturer specifications Use Scenarios: 1. When your blower only operates on the speed setting, replacing the resistor restores all speed options. 2. If your fan stops operating altogether, this resistor can solve the issue and get your HVAC system working again. 3. For drivers who experience inconsistent airflow or difficulty adjusting cabin comfort, installing a resistor returns smooth, responsive fan control. Functionality: The blower motor resistor regulates the electrical current that controls the speeds of the HVAC fan. A faulty resistor disrupts this regulation, leading to limited or no speed control. Timely replacement ensures HVAC performance and a comfortable driving environment. Fitment: Designed for direct plugandplay replacement with 2013 Dodge Dart models that match the listed OEM part numbers. Quality Assurance: Manufactured to standards to provide longterm, dependable service. Meets original equipment quality in design and performance.
