Review: 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. I had to go out of my way to get the correct screws for the job. Other than that awesome product.
Review: Fit perfect. Worked perfect. This is the 3rd brand I've tried in about 18 months. Hopefully it lasts longer that previous 2.

- 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
