- Use a multimeter to check for voltage at the connector when the HVAC system is set to the highest fan setting.
- If voltage is present but the motor does not run, it is likely defective and needs replacement.
Step 4: Check the Resistor
The blower motor resistor controls the fan speed. If it fails, you might experience issues with different speed settings.
How to Diagnose the Resistor
- Locate the resistor, often positioned near the blower motor.
- Disconnect the wiring connector.
- Use a multimeter to test the resistor for continuity.
- If there’s no continuity, the resistor is faulty and should be replaced.
