FORD Explorer — What to know
The Explorer is Ford's mid-size SUV with a broad service network. The 3.5 EcoBoost V6 (2011–2019) is the most popular engine and is generally reliable. Known issues include cabin exhaust fume intrusion on 2011–2017 models and carbon buildup on EcoBoost direct injection engines.
What is this repair?
Plain-English overview
The blower motor forces air through the heating and air conditioning system into the cabin; the resistor controls fan speed. A failed motor means no airflow at all; a failed resistor typically causes the fan to work only on its highest setting.
Warning signs
How to tell your FORD Explorer needs this repair
- No airflow from any vent regardless of fan speed setting (motor failed)
- Fan only works on the highest speed setting (resistor failed)
- Unusual noise from the dashboard area — squealing, rattling or humming
- Airflow noticeably weaker than before
- Burning smell from the vents when the fan is switched on
Common causes
Why FORD Explorer vehicles need this repair
- 1.Normal component wear over high mileage
- 2.Oil maintenance quality and adherence to change intervals
- 3.Operating temperature and thermal cycling over time
- 4.Age degrading seals, gaskets and rubber components
What affects the price
Why your quote may differ
- Whether the motor or resistor has failed (resistor is much cheaper)
- Accessibility of the blower housing — some require dashboard removal
- Whether the cabin air filter is also blocked and contributed to motor failure
