What Symptoms Indicate a Faulty A/C Blower Motor Relay Fuse in a 2015 Explorer?
A faulty A/C blower motor relay fuse in a 2015 Explorer can exhibit several symptoms, indicating that it may need attention.
- Blower motor fails to operate.
- Blower motor operates intermittently.
- Blower motor operates only at certain speeds.
- Air conditioning functions but without airflow.
- Unusual noises from the blower motor.
These symptoms can vary in severity and may occur simultaneously. It is important to diagnose the issue accurately to understand whether the relay, fuse, or another component is failing.
-
Blower Motor Fails to Operate: A non-functioning blower motor is a primary sign of a faulty relay fuse. If the A/C system is turned on but no airflow is present, the relay may not be delivering power to the blower motor. According to an Automotive Repair Study by J.D. Power (2021), this is one of the most common failures reported by vehicle owners.
-
Blower Motor Operates Intermittently: If the blower motor functions sporadically, this may indicate a failing relay. Poor electrical connections or a malfunctioning fuse can cause abrupt on-and-off behavior. For instance, several users reported this issue on automotive forums as being linked to their fuse’s deterioration due to heat exposure.
-
Blower Motor Operates Only at Certain Speeds: This symptom points to a problem either with the relay or the blower resistor. When the motor does not work across all speeds, it indicates that voltage levels may not be correctly regulated. The National Highway Traffic Safety Administration (NHTSA) mentions that inconsistent airflow often aligns with relay relay issues.
-
Air Conditioning Functions but Without Airflow: This scenario suggests the compressor is working, but the blower motor is failing to deliver air. A functional compressor indicates that the A/C system is charged properly, but troubleshooting the relay fuse becomes critical if there’s no airflow.
-
Unusual Noises from the Blower Motor: Strange sounds can indicate physical issues with the blower motor or electrical problems linked to the relay. Noise may arise from a failing component that the relay is supposed to power.
Understanding these symptoms can enhance troubleshooting efforts and ensure the correct repair is undertaken in a timely manner. Regular maintenance checks can also prevent these issues from occurring.
How Can You Troubleshoot Issues With the A/C Blower Motor Relay Fuse in a 2015 Ford Explorer?
To troubleshoot issues with the A/C blower motor relay fuse in a 2015 Ford Explorer, follow these steps: check for blown fuses, test the relay, inspect wiring connections, and assess the blower motor condition.

-
Visual Inspection of the Fuse: Visual inspection of the fuse involves checking for any obvious signs of damage. You should look for discoloration, a broken filament, or corrosion. This method is simple yet effective for an initial assessment. If the fuse appears damaged, replacing it may resolve the issue.
-
Multimeter Testing: Multimeter testing checks the fuse for electrical continuity. Set the multimeter to the resistance setting and measure the resistance across the fuse. A reading of zero ohms indicates that the fuse is functioning. If the reading is infinite, the fuse is blown, and replacement is necessary. This method provides a clear and precise diagnosis of the fuse’s health.
-
Circuit Continuity Test: The circuit continuity test involves checking the entire pathway from the relay to the blower motor. Using a multimeter, you would follow the circuit, testing each connection point for continuity. If any break exists, that section may need repair or replacement. It is critical for locating faults within the circuit.
-
A/C System Pressure Test: A/c system pressure tests evaluate whether there is adequate refrigerant pressure in the system. Low pressure can prevent the blower motor from functioning, mimicking relay issues. Use a pressure gauge to check the low and high sides of the A/C system. Low readings may indicate a refrigerant leak or insufficient refrigerant, which may need to be charged before further troubleshooting the relay.
-
Relay Function Test: Relay function tests involve applying power directly to the relay. If the relay does not activate the blower motor when supplied with power, the relay may be faulty. This test requires basic electrical knowledge and a voltage source and can confirm whether the relay itself is problematic.
These diagnostic tests can systematically determine the cause of A/C blower motor issues related to the relay and fuse, allowing for effective troubleshooting and repairs.

Why Is It Important to Address A/C Blower Motor Relay Fuse Issues Promptly?
Why Is It Important to Address A/C Blower Motor Relay Fuse Issues Promptly?
It is important to address A/C blower motor relay fuse issues promptly to ensure the effective operation of your vehicle’s air conditioning system. Delays in fixing these issues can lead to system failures, decreased comfort, and potentially more expensive repairs down the line.
The National Institute for Automotive Service Excellence (ASE) defines a relay as an electrical switch that uses an electromagnet to control a high-current circuit. In the context of an A/C system, the blower motor relay fuse protects the electrical circuit that powers the blower motor, which is essential for circulating air through the vehicle’s HVAC (Heating, Ventilation, and Air Conditioning) system.
Underlying causes of A/C blower motor relay fuse issues can include electrical overloads, short circuits, or wear and tear on components. For example, if the blower motor draws excessive current due to a blockage in the fan or electrical faults, it can cause the relay fuse to blow. This protects other components from damage but also prevents the air conditioning system from working.
The term “relay fuse” refers to a protective device in an electrical circuit. It prevents excess current from passing through to sensitive components. If a fuse blows, it interrupts the electrical flow, meaning that systems reliant on that flow, like the A/C blower motor, will cease to function until the issue is resolved.
When the blower motor relay fuse fails, the A/C system can experience various effects. The blower motor may stop working altogether, leading to no airflow from the vents. This situation can be particularly uncomfortable in hot weather, increasing driver distraction and discomfort. Additionally, prolonged operation under electrical stress can damage the blower motor itself, leading to costly replacement.
Certain conditions can contribute to this issue. For example, debris blocking the A/C intake can increase the load on the blower motor. Another scenario is a faulty blower motor resistor, which can cause the motor to draw more current than usual. Regular maintenance can help identify these issues early, but if they are not addressed promptly, they may lead to further complications, such as system overheating or complete failure of the A/C system.
