It is sure to easy installation and safe operation - Working Principle: The blower motor resistor is an important component in an automotive heating,ventilation and air conditioning systerm ( HVAC systerm ) . The ac blower motor resistor is responsible for controlling the blower motor speed. When you adjust the speed of the fan in the car, you are actually adjusting the current that the a/c blower motor resistor allows to reach the fan motor. The higher the fan speed setting, the greater the electrical flow allowed through, and the faster the fan motor speed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DGS1VJSD | | Are batteries included? | No | | Brand | Marsflex | | Customer Reviews | 4.4 4.4 out of 5 stars (98) | | Date First Available | 21 November 2024 | | Horsepower | 228 Watts | | Included Components | 1 blower resistor | | Item Weight | 272 g | | Item model number | APAC05074 | | Manufacturer | Marsmotor | | Model number | APAC05074 | | Number of Memory Sticks | 1 | | Product Dimensions | 11W x 7H Centimeters | | Speed | 3250 RPM | | Voltage | 12 Volts | | Wattage | 228 Watts | ## Product Details - **Brand:** Marsflex - **Horsepower:** 228 Watts - **Product Dimensions:** 11W x 7H Centimeters - **Speed:** 3250 RPM - **Voltage:** 12 Volts ## Images ![Marsflex Blower Motor Resistor 1581773 2003 2004 2005 2006 2007 for Chevy Chevrolet Tahoe Silverado Trailblazer Avalanche, for GMC Sierra Yukon, Blower Resistor 973-508 89018653 for Auto AC Control - Image 1](https://m.media-amazon.com/images/I/71C7M3YgjuL.jpg) ## Questions & Answers **Q: How to judge whether this resistor is suitable for my vehicle?** A: Step 1: Before buying, please be sure to check the appearance of the blower resistor on your car and whether OE part number is the same as the blower resistor you bought! **Q: Is this resistor suitable for Auto AC Control or Manual AC Control cars?** A: Auto AC Control. **Q: Does the resistor I received have wiring harness and other parts?** A: There are one resistor, wiring harness and some parts in this package you received. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***. on 5 December 2025* Fixed my problem and haven’t had any issues other than I wish the screws that came with it were about half an inch longer.
