Ford Explorer HVAC Blower Motor Resistor Guide for 2009-2015 Models
If your Explorer's fan only works on high or has erratic speeds, this guide is for you.
- First, confirm your Explorer's generation: 2009-2010 (truck-based) and 2011-2015 (crossover) use different parts.
- The classic symptom of failure is the fan only working on the highest speed setting.
- Always inspect the wiring connector for melting or corrosion and replace it if damaged to prevent repeat failure.
- This is a very easy DIY repair that can be done in under an hour with basic tools.
Is Your Explorer's Fan Acting Up?
If your Ford Explorer's climate control fan only blows on the highest setting, won't work on certain speeds, or changes speed by itself, the problem is almost certainly a failed HVAC blower motor resistor. This is a common issue, and thankfully, it's a simple and inexpensive part to replace yourself.
Critical: Two Explorer Generations, Two Different Parts
The 2009-2015 year range covers two completely different Ford Explorer models. The parts are NOT interchangeable. You must identify your vehicle's generation before ordering.
- 2009-2010 Ford Explorer (Fourth Generation): This is the older, truck-based body style. The resistor is a traditional coil-and-wire type located behind the glove box. 🎬 Watch this step-by-step guide for 2009-2010 Explorer models.
- 2011-2015 Ford Explorer (Fifth Generation): This is the modern, unibody crossover style. It uses an electronic control module located under the passenger side dash, near the blower motor.
Common Failure Symptoms
A failing blower motor resistor will show clear signs. The most common symptom is the fan only working on the highest speed. This happens because the high setting bypasses the resistor, while all lower speeds depend on it. Other symptoms include:
- Fan only works on some speeds, but not others.
- Fan speed changes on its own or is inconsistent (common on 2011+ models).
- No air blows from the vents on any speed.
- Fan won't turn off, even with the key out.
Choosing the Right Aftermarket Resistor
While Motorcraft is the original Ford part, several quality aftermarket brands offer excellent value. Here’s how they stack up for your Explorer:
- Top Tier (OEM Equivalent): Motorcraft is the factory part and the benchmark for fit and quality. If you want a guaranteed match with no compromises, this is the choice.
- Excellent Aftermarket (with a Bonus): Dorman is a highly respected aftermarket brand. Crucially, they often sell kits that include a new wiring harness pigtail. The connector is a frequent failure point due to heat, so replacing it at the same time is a smart move, especially for 2011-2015 models as noted in Ford's Technical Service Bulletin (TSB) SSM 48070. 🎬 See how to replace the resistor and the wiring harness.
- Standard Aftermarket: Brands like Four Seasons, Standard Ignition (SMP), Holstein, and Global Parts (GPD) are all reputable manufacturers of climate control components. They offer a direct replacement for the original part and are a reliable, budget-friendly choice.
Pro Tip: Replace the Connector
An aging blower motor can draw too much electricity, causing the resistor and its electrical connector to overheat and melt. Always inspect the connector when replacing the resistor. If it shows any signs of melting, browning, or corrosion, you must replace it to prevent the new resistor from failing prematurely.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $44.17 - $110.83 |
| New OEM (Motorcraft) | $50 - $130 |
| Shop Labor | $90 - $150 |
Frequently Asked Questions (FAQ)
Is this a difficult part to replace myself?
No, this is a great DIY job for beginners. For 2009-2010 models, you'll need to lower the glove box to access the resistor. For 2011-2015 models, you'll work under the passenger side dash. The main challenge is the tight space, but it only requires basic hand tools (typically 7mm and 8mm sockets). The entire job usually takes less than an hour.
Is there a recall on the blower motor resistor?
There is no direct recall for the resistor itself. However, Ford has issued recalls and TSBs for related parts. TSB SSM 48070 for 2011-2019 Explorers notes that a bad electrical connector can cause the resistor to fail and recommends replacing both. Other Ford models have had recalls on the blower *motor* for being a fire risk, which can damage the resistor. Because of this, it's critical to inspect the wiring for damage.
Why did my blower motor resistor fail?
Resistors generate heat as part of their normal operation and can simply wear out over time. However, the most common cause of premature failure is an old blower motor. As the motor ages, it draws more electrical current, which overloads the resistor and causes it to burn out. If you've replaced the resistor before, your blower motor is likely the root cause.
🎬 Learn how to diagnose and replace the blower motor yourself.Do I need to replace the blower motor at the same time?
It is highly recommended, especially if this isn't the first time the resistor has failed. Replacing both at the same time ensures the new resistor won't be immediately damaged by a faulty, power-hungry motor. It saves you from having to do the job twice.
