Warranty: 1-year warranty. Package includes 1 ac blower motor resistor and a wire harness. Do not hesitate to contact us if you have any doubts or queries

Working Principle: The blower motor resistor is an important component in an automotive heating,ventilation and air conditioning 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

Advantage: All GVPART4U blower motor resistors meet or exceed OE design and performance. Strict testing procedure and superior materials that provide maximum strength and durability. The quality, durability and reliability of all products are backed by over 50 years of excellence in experience. It is sure to easy installation and safe operation

Q: Is there anything special about this resistor, such as its compatibility and installation requirements? A: Thank you for choosing GVPART4U! Before buying, please pay attention to this following item, which is the top priority! Before purchasing, please verify not only vehicle compatibility and whether your air conditioning system is equipped with Auto AC Control, but also pay close attention to the product’s physical specifications—including mounting holes, the pin count of both the resistor plug and harness connector—as well as the OE number.(Because the blower resistor you bought is suitable for the same vehicle as the other 3 different blower resistors!!!If you don't check these details, you will easily buy the wrong product!!!) Only when all these details match is this blower motor resistor compatible with your vehicle. Beside, the installation of the GVPART4U blower motor resistor is quick and straightforward; most customers report completing the process in just 3–10 minutes!
