Does the blower motor resistor control heat?
The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed.
Does blower motor resistor affect AC?
A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system.
How long should a blower resistor last?
The blower motor resistor is designed to last for the car’s lifespan. In most cases, these resistors will wear out long before the car does. Usually, the wear that the blower motor resistor has is due to the constant use that it gets and the heat that it is exposed on a regular basis.
What makes a resistor go bad?
A fixed composition resistor normally fails in an open configuration when overheated or overly stressed due to shock or vibration. Excessive humidity may cause an increase in resistance. A variable composition resistor may wear after extensive use, and worn away particles may cause high resistance short circuits.
What does the blower motor resistor do on a Chevy Silverado?
The blower motor resistor in your Chevy Silverado controls the speed of the blower motor in your truck. When you adjust the fan speed control for more hot or cool air, the blower motor resistor adjusts the amount of electrical resistance. This controls the amount of power sent to the blower motor, controlling the speed.
How does a blower motor resistor work?
When you adjust the fan speed control for more hot or cool air, the blower motor resistor adjusts the amount of electrical resistance. This controls the amount of power sent to the blower motor, controlling the speed.
Why is my Chevy Silverado blower motor stuck on one speed?
If the blower motor in your Silverado only works on certain speeds or it appears to be stuck on one speed, you may have a problem with the blower motor resistor or the connector. O’Reilly Auto Parts carries replacement blower motor resistors, blower motors, and fuses for your Silverado so you can restore comfort to your interior.
