The blower motor resistor in a 2008 Chrysler Sebring is located under the passenger side dashboard. It is attached to the HVAC housing near the blower motor. This resistor controls the speed of the blower motor. You might need to remove the under-dash cover to access it for vehicle maintenance or automotive repair.
Once located, check for signs of damage or corrosion. If you find any issues, it is time to replace the resistor. To do this, disconnect the wiring harness and unscrew the resistor from its mount. Install the new resistor by reversing this process. Secure the wiring harness and reattach the dashboard panel.
Replacing the blower motor resistor can restore proper airflow and control over the AC system. After the replacement, reconnect the negative battery cable. Finally, test the AC system to ensure it operates correctly.
In the next section, we will discuss common symptoms of a malfunctioning AC blower motor resistor in the Chrysler Sebring and how to identify potential problems early.
What Is the Role of the AC Blower Motor Resistor in a Chrysler Sebring?
The AC blower motor resistor in a Chrysler Sebring regulates the speed of the vehicle’s blower motor. It controls the airflow through the heating and air conditioning system, allowing for different fan speeds.
According to the Chrysler Owner’s Manual, the blower motor resistor is essential for controlling variable fan speeds. This component ensures that drivers can adjust cabin air comfort according to their preferences.
The AC blower motor resistor accomplishes its task by using resistors to manage the electrical current flowing to the blower motor. Different resistor values correspond to different fan speeds. When one resistor fails, it can cause the blower to operate at only one speed or stop functioning entirely.
The National Highway Traffic Safety Administration (NHTSA) describes motor resistors as critical for vehicle climate control systems. Proper functioning ensures driver visibility and comfort during varied weather conditions.
Common issues leading to blower motor resistor failure include overheating, electrical short circuits, and corrosion from moisture. These conditions can shorten the component’s lifespan and reduce performance.
Data from the Automotive Aftermarket Suppliers Association indicates that blower motor resistor replacements increase during peak usage months, such as summer and winter. This trend reflects the importance of this component in maintaining comfort in vehicles.
A malfunctioning blower motor resistor can lead to inadequate temperature control in the cabin. This may also affect visibility if windows fog up or ice over, creating dangerous driving conditions.
The impact of a faulty resistor can extend to higher repair costs and customer dissatisfaction. Ensuring proper maintenance can help avoid these problems.
To mitigate these issues, it is advisable to perform regular inspections of the HVAC system. Recommendations from automotive experts include checking electrical connections and resealing areas prone to moisture.
Specific strategies for maintaining the AC system involve regularly replacing cabin air filters and using quality parts for replacements. Monitoring the blower motor’s operational sounds can also prevent issues before they escalate.

What Are the Common Symptoms of a Faulty AC Blower Motor Resistor in a Chrysler Sebring?
The common symptoms of a faulty AC blower motor resistor in a Chrysler Sebring include inconsistent airflow, complete loss of airflow, and blower motor operation only at high speed.
- Inconsistent airflow
- Complete loss of airflow
- Blower motor operates only on high speed
- Intermittent fan operation
- Unusual noises from the blower motor
These symptoms can impact the comfort level in the vehicle and may indicate other underlying issues. Understanding the specific symptoms can help in diagnosing the problem accurately.
-
Inconsistent Airflow:
Inconsistent airflow occurs when the fan speed does not adjust according to the selected settings. This symptom may be indicative of a malfunctioning resistor that fails to regulate the voltage effectively. The resistor controls the current flowing to the blower motor, and if it is faulty, it may not provide the correct amount of power needed for different speeds. -
Complete Loss of Airflow:
A complete loss of airflow signifies that the blower motor is not functioning at all. This may happen if the resistor fails completely or there is a break in the electrical circuit feeding the motor. In a 2019 report by Consumer Reports, many car owners experienced complete airflow failures due to defective components in the AC system. -
Blower Motor Operates Only on High Speed:
Blower motors that only work on high speed indicate that lower speeds are not receiving the necessary voltage. This issue generally points towards a faulty blower motor resistor. As the resistor controls which circuit is engaged, the failure to operate at low speeds is an often-noted symptom across various car makes and models. -
Intermittent Fan Operation:
Intermittent operation occurs when the blower motor sometimes works and sometimes does not. The resistor may be partially functioning, leading to erratic performance. As noted in a study by the Automotive Research Center, such irregularities can stem from poor electrical connections or damage to the resistor itself. -
Unusual Noises from the Blower Motor:
Unusual noises may arise from a failing blower motor or associated components due to vibration or debris caught in the motor. When the resistor impacts motor performance, it can exacerbate existing issues, leading to undesirable sounds. Observations by auto technicians emphasize that noise complaints are often related to multiple failures in the HVAC system and should be diagnosed promptly to avoid further damage.
