When do you need to replace the fan resistor?
When do you need to replace the fan resistor?
If your interior AC/ Heat fan is not working on low, or one of the fan settings is not working, then you probably need to replace the blower motor resistor. This video will go though all of the steps. Is your blower fan working only on the max (4 speed)? This is a common problem with the Volkswagen, Audi, Seat, Skoda cars.
How to remove a blower motor from an Audi A4?
Open the glove box and remove the three 8mm screws along the upper ledge of the glove box (red arrows). Remove the two 8mm screws on the lower section of the glove box (red arrows). Next, use the 8mm socket and remove the single screw on the side (red arrow). With the glove box open remove the four 8mm screws inside the glove box (red arrows).
When to replace the blower motor on a hamster wheel?
If the blower motor starts making noise when you turn the fan on, there is a very good chance it is starting to go bad and will need to be replaced. While it is possible to lubricate the blower motor’s shafts around the hamster wheel this is usually only a temporary fix and you have to catch it right away.
Why does my blower not run at top speed?
If your blower motor will not run at top speed the most likely culprit is a bad resistor pack. The resistor works in conjunction with the motor and system to control the speed and therefore volume of air moving through the system.
Why does blower motor resistor keep going out?
The blower motor appears to be defective here. When the brushes wear out the motor draws excessive amps which could cause the resistor to burn out. Before making further replacements remove the motor and check it, especially the brush assembly. This is the most likely reason for the resistor to fail repetitively.
How much does a blower motor cost?
Based on these factors, the costs, including both parts and labor, can range anywhere from $250 to more than $500 for a standard single speed blower motor. If a blower motor is required for a more expensive unit, such as a variable-speed motor, then the costs could be more than $1,000; however, these motors tend to be relatively rare.
Where is the resistor for the blower motor located?
Two individual resistors make up the blower motor resistor assembly on your Chevy pickup. As you’re probably already aware, these resistors are located between the A/C-Heater control panel and the blower motor . The purpose of these resistors is to reduce the amount of the blower motor’s current that’s passing through them.
What does a blower motor resistor do?
Definition. A blower motor resistor, typically located beneath the passenger side dashboard, contains three resistors, or sets of terminals designed to generate voltage in proportion to electrical current. These resistors allow the blower motor to function at lower speeds.
