Function And Typical Symptoms
The blower supplies conditioned air from the HVAC unit into the passenger compartment. Common symptoms of a failing blower include reduced or no airflow from the vents, unusual bearing or brush noise, intermittent operation, or complete stoppage. Since the resistor is included, the unit supports multiple fan speeds; resistor failure can lead to loss of specific speed settings (typically low-speed loss).
How The Part Is Replaced
Replacement is straightforward for experienced technicians and competent DIYers familiar with interior trim removal. Typical steps:
- Disconnect the negative battery terminal before starting work to avoid electrical shorts.
- Remove lower passenger-side trim panels and glovebox as required to access the blower housing.
- Unplug the electrical connector and remove fastening screws securing the blower assembly.
- Withdraw the blower motor and resistor assembly from the housing. Replace the old unit with the new one, ensuring the resistor is properly seated if fitted separately.
- Reconnect the electrical connector, test the blower operation through all speed settings, then refit panels and reconnect the battery.
Installation Recommendations
- Always disconnect the battery before beginning work and follow manufacturer trim-removal procedures to avoid damaging clips or panels.
- Inspect the air intake and ducting for leaves, debris or water ingress and clear any blockages before installing the new blower.
- Check the cabin filter condition; a clogged filter increases load on the blower and shortens its service life.
- After installation, verify operation across all fan speeds and ensure no unusual noises are present.
Why It Fails Most Often
Typical causes of failure are worn brushes and bearings due to long-term use, contamination from debris or water entering the HVAC intake, and overheating or failure of the resistor pack. Vehicles used in dusty environments or with blocked drains are more prone to premature blower motor wear. Addressing the root cause (cleaning ducts, replacing the cabin filter, ensuring proper drainage) helps prevent repeat failures.
Ordering Notes
