What should I do if my blower motor fails?
What should I do if my blower motor fails?
If your blower motor fails, replace the blower and resistor together. You don’t want to have to go back in if one fails later. Over time, a blower motor may become noisy as the motor electrical contacts wear. The blower fan cages also fracture, creating a vibration when the blower is ON.
When to replace blower motor and resistor together?
The blower motor is a D/C electric motor driven by varying current supplied by the blower motor final stage unit. If your blower motor fails, replace the blower and resistor together. You don’t want to have to go back in if one fails later. Over time, a blower motor may become noisy as the motor electrical contacts wear.
What kind of motor is a blower motor?
The blower motor is a D/C electric motor driven by varying current supplied by the blower motor final stage unit. If your blower motor fails, replace the blower and resistor together. You don’t want to have to go back in if one fails later.
Where is the blower motor resistor located on a BMW?
When leaving a comment, please leave your vehicle information. The blower motor is located behind the center of the dashboard and is serviced from the interior of the vehicle. The blower motor resistor is mounted to the rear of the blower motor. Remove the IHKA control panel, radio and seat heat controls.
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.
