Direct replacement part designed for precise fit and reliable operation. Prevents further damage to HVAC components by ensuring correct electrical load handling. Helps maintain cabin comfort by allowing full range of fan speed operation. Function and Performance: The blower motor resistor regulates the electrical current flowing to the blower motor, controlling fan speeds from low to . When it fails, your fan may only work on a single speed or stop working entirely, making it difficult to heat or cool your vehicle properly. This replacement resistor solves that problem by restoring full fan speed control, ensuring consistent temperature regulation in any driving condition. Common Use Scenarios: 1. Restoring temperature control after the fan only works on speed. 2. Fixing the issue where the blower does not operate at all on certain speed settings. 3. Preventing premature failure of the blower motor due to improper electrical regulation. Installation and Fit: Designed for quick, straightforward installation as a directfit replacement for the listed OEM part numbers. Fits securely within factory connection points with no modification required. Material and Build Quality: Manufactured to meet or exceed OEM specifications for durability, heat resistance, and electrical performance, ensuring dependable longterm operation. If your vehicle's blower motor functions only on certain speeds or has stopped working on some settings, replacing the blower motor resistor is a proven solution to restore full HVAC performance.
