A Guide to the 2007-2012 Ford Edge HVAC Blower Motor Resistor
If your climate control fan speeds are not working correctly, the blower motor resistor is the most likely reason.
- The most common symptom of failure is the fan only working on the high setting.
- This is an easy DIY replacement located behind the passenger side glove box that takes less than 30 minutes.
- Always inspect the wiring connector for melting; if damaged, buy a kit that includes a new pigtail harness.
- To prevent repeat failures, it is highly recommended to replace the blower motor at the same time as the resistor.
Is Your Ford Edge Blower Fan Acting Up?
A common issue for 2007-2012 Ford Edge owners is a problem with the heating and air conditioning fan. You might notice that the fan only blows on the highest setting, or that some speeds don't work at all. These are classic signs that the HVAC Blower Motor Resistor has failed. This component is responsible for controlling fan speed, and when it breaks, it can leave you with limited or no control over the airflow in your cabin.
Common Symptoms of Failure
Look out for these specific signs that point to a bad blower motor resistor 🎬 Watch this video to identify common blower motor resistor symptoms. in your Edge:
- Fan Only Works on High: This is the most common symptom. The high setting has a direct connection to power that bypasses the resistor, so it's the only one that works when the resistor's internal circuits have failed.
- Some Fan Speeds Don't Work: You may lose one or more of the lower or medium speeds while others still function.
- No Air From Vents at Any Speed: In some cases, a complete failure of the resistor can prevent the blower motor from running at all. Before assuming it's the resistor, it's a good idea to check the blower motor fuse first.
- Burning Smell From Vents: An overheating resistor or its wiring connector can create a plastic or electrical burning smell. This is a serious sign and should be inspected immediately, as it can be a fire hazard.
A Note on Recalls and Related Issues
While there are no specific recalls for the blower motor resistor on the 2007-2012 Ford Edge, Ford has issued recalls for the blower motor itself on other models and years due to risks of overheating and fire. A failing blower motor can draw too much electrical current, causing the new resistor to overheat and fail prematurely. For this reason, it is highly recommended to inspect the blower motor and consider replacing it at the same time as the resistor, especially if the old resistor shows signs of melting or burning.
Choosing the Right Aftermarket Part
When replacing the blower motor resistor, you have several options besides the original equipment (OEM) Motorcraft part. Aftermarket brands offer a range of quality and price points.
| Brand Tier | Brands | General Quality & Cost |
|---|---|---|
| Premium Aftermarket | Standard Ignition, Dorman | These brands are well-regarded and often engineer their parts to meet or exceed OEM specifications. Dorman frequently includes a new wiring harness, which is crucial if the original connector is melted or corroded. Expect to pay a bit more for this quality. |
| Standard Aftermarket | Four Seasons, Global Parts (GPD) | These brands offer a good balance of quality and value. They are a reliable choice for most daily drivers and are often manufactured to be a direct fit. Some forum users have mixed opinions on Four Seasons, but many find them to be a suitable replacement. |
| OEM | Motorcraft | This is the original part your Edge was built with. It guarantees perfect fit and function but comes at the highest cost. If you want the peace of mind of using a factory part, Motorcraft is the way to go. |
Pro Tip: Check the Connector!
Before ordering your new resistor, inspect the electrical connector attached to it. If you see any signs of melting, browning, or corrosion, you MUST replace the connector (pigtail) as well. Many aftermarket kits from brands like Dorman include a new connector for this reason. Failure to replace a damaged connector will cause the new resistor to fail quickly.
Frequently Asked Questions
Can I replace the blower motor resistor myself?
Yes, this is a very DIY-friendly job. The resistor is located on the passenger side, behind the glove box. It is typically held in by two screws. The process involves removing the glove box, unplugging the two electrical connectors, removing the screws, and swapping the part. The entire job can usually be done in under 30 minutes with basic tools 🎬 Follow this step-by-step guide to replace your Ford Edge resistor. like a Phillips head screwdriver.
Why did my new resistor fail after only a few months?
The most common cause for repeat resistor failure is an old blower motor that is drawing too much electrical current 🎬 Learn how to prevent your new resistor from failing again.. The motor gets harder to spin as it ages, which pulls more power through the resistor and causes it to overheat and burn out. If you're on your second resistor, you should replace the blower motor as well. Another cause is a melted or corroded wiring harness connector that wasn't replaced with the resistor.
Is there a difference between a blower motor resistor and a blower motor control module?
Yes. Your 2007-2012 Ford Edge uses a traditional blower motor resistor if it has manual climate controls (with a knob that has set fan speeds like Low, Med, High). If your Edge has Electronic Automatic Temperature Control (EATC), where you set a specific temperature, it uses a more complex electronic Blower Motor Control Module to provide variable fan speeds. While they perform the same basic function, they are not interchangeable. This guide focuses on the resistor for manual systems.
Do I need to replace the blower motor at the same time?
It is strongly recommended. A failing blower motor is the primary cause of resistor failure. Replacing both parts at the same time is the best way to ensure a long-lasting repair and prevent the new resistor from burning out prematurely. A blower motor replacement costs around $164 for the part and is also located in the same area as the resistor.
