All 1 Known Issues
On the 2014-2019 Toyota Highlander, the HVAC blower motor in 3rd-generation Highlanders commonly fails or operates intermittently. The blower motor resistor overheats and burns out, causing the fan to work only on the highest speed setting or stop completely. Moisture intrusion through the cabin air filter housing accelerates corrosion.
Common Symptoms
- Blower only works on highest speed setting
- No airflow from any vent
- Burning smell from dashboard vents
- Intermittent blower operation
- Squealing noise from blower area
How to Fix
Replace the blower motor and blower motor resistor together. Clean any debris from the cabin air filter housing and ensure the drain is clear. An updated resistor design (Toyota part 87138-0E040) has improved thermal management.
