Reasons Why 2017 Ford Expedition Blower Motor Not Working

Here are the reasons:

Blower Motor Fuse

The blower motor fuse is a 20-amp fuse located in the under-hood fuse box. If the fuse is blown, the blower motor will not work. To check the fuse, remove it from the fuse box and visually inspect it for damage. If the fuse is blown, replace it with a new one.

Blower Motor Relay

The blower motor relay is a small, cylindrical device located in the under-hood fuse box. It receives power from the fuse box and sends it to the blower motor. If the relay is faulty, the blower motor will not work. To check the relay, remove it from the fuse box and test it with a multimeter. If the relay is faulty, replace it with a new one.

Blower Motor Control Module

The blower motor control module is a small, electronic device that controls the speed of the blower motor. It receives input from the HVAC control panel and sends a signal to the blower motor to turn on and off and to adjust the speed. If the control module is faulty, the blower motor will not work. To check the control module, you will need to use a diagnostic tool to scan for codes. If there are any codes related to the blower motor control module, the module will need to be replaced.

Blower Motor Wiring

The blower motor is wired to the fuse box, the blower motor relay, and the blower motor control module. If there is a problem with the wiring, the blower motor will not work. To check the wiring, you will need to use a multimeter to check for continuity between the different components. If there is no continuity, the wiring will need to be repaired or replaced.

How to Troubleshoot: 2017 Ford Expedition Blower Motor Not Working

Check the Blower Motor Fuse

First
start by checking the blower motor fuse in the fuse box. Locate the fuse box
usually found under the dashboard or in the engine compartment. Use the owner’s manual to identify the blower motor fuse. If the fuse is blown
replace it with a fuse of the same rating.

Inspect the Blower Motor Resistor

The blower motor resistor controls the speed of the blower motor. If the blower motor is not working
the resistor may be the culprit. The resistor is often located near the blower motor or in the HVAC ducting. Use a multimeter to test the continuity of the resistor. If it’s faulty
replace it with a new one.

Test the Blower Motor Relay

The blower motor relay is responsible for switching the power to the blower motor. Locate the relay in the fuse box and test it using a relay tester or multimeter. If the relay is faulty
replace it with a new one to restore power to the blower motor.

Examine the Blower Motor Connector

The blower motor connector may have become loose or corroded
leading to a loss of power to the motor. Inspect the connector for any signs of damage or corrosion. If necessary
clean the connector and ensure a secure connection to restore power to the blower motor.

Check the HVAC Control Module

The HVAC control module regulates the operation of the blower motor. If the blower motor is not working
the control module may be malfunctioning. Use a diagnostic scan tool to check for any fault codes related to the HVAC system. If the control module is faulty
it may need to be replaced or reprogrammed.

Conclusion

Troubleshooting a 2017 Ford Expedition blower motor that’s not working involves a systematic approach to identify and resolve the underlying issue. By checking the fuse
resistor
relay
connector
and control module
you can diagnose the problem and take the necessary steps to restore the functionality of the blower motor. If the issue persists
seeking assistance from a qualified automotive technician is recommended to ensure a thorough diagnosis and resolution of the problem.
