How do you change a blower motor resistor?
Difficulty
- Remove the negative battery terminal.
- Locate the blower motor resistor on the passenger side under the dash board.
- Disconnect the electrical connector to the blower motor resistor.
- Remove the screws or bolts to the blower motor resistor and remove the resistor.
- Installation is the reverse of the removal.
How long does it take to replace a AC blower motor?
This is around a 4 hour job by an experienced Tech. At home, by a Novice with decent skills, about 5 hours plus!
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.
