What does a blower control module do?
An A/C fan control module helps to control the blower that supplies air to the cabin of a vehicle, as well as the cooling fans. The module helps to make sure that the cool air that is produced within the A/C system of a car is blown into the cabin.
How do you replace a blower motor resistor module?
How to Replace a Blower Motor Resistor
- 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.
What causes a blower motor resistor to burn out?
In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.
Can a blower motor resistor be repaired?
The resistor module is easy and inexpensive to replace. It’s then typically installed in the ductwork, near the car blower—either under the dash or under the hood. (Refer to a service manual to locate yours.) Purchase a new resistor module at the auto parts store (usually less than $25).
How do you diagnose a bad climate control module?
Symptoms of a Bad or Failing AC Control Module
- Inconsistent cooling. Because the AC control module controls and regulates all of the functions of the system, you may begin to notice cooling inconsistencies when there is a problem.
- Out-of-date software updates.
- Uneven air distribution.
Where is the blower motor resistor module located on the Subaru Imprezza?
Where is the blower motor resistor module located on the Subaru Imprezza? The blower resistor can be found below the dashboard on the passenger side of the Subaru. It has a four wire flat connector and two screws and can be accessed by removing the glove box or laying on your back and looking up from under the dashboard.
Where is the blower resistor on a Subaru Outback?
The blower resistor can be found below the dashboard on the passenger side of the Subaru. It has a four wire flat connector and two screws and can be accessed by removing the glove box or laying on your back and looking up from under the dashboard. How to replace the blower motor on a Subaru Outback Legacy?
How can I tell if my Subaru blower motor is faulty?
To determine which of the two, switch the blower to high speed and the blower motor should be unplugged. One of the wires in the connector should read around 12 volts and the other should be a good ground. If both show good, then the blower motor is faulty. If it does not show, the resistor is probably defective.
