Dodge Durango HVAC Blower Motor Resistor Guide: 1998-2009
Is your Durango's fan stuck on high or not working at all? Here's the mechanic's take on a permanent fix.
- The most common symptom of failure is the fan only working on the 'High' setting.
- For a permanent fix, you must replace the resistor, the blower motor, and the wiring connector pigtail together.
- A burning smell from the vents indicates a melting connector and is a potential fire hazard that requires immediate attention.
- Before buying, physically check if the resistor is under the passenger dash, especially on 1998-2003 models, to ensure you get the right part.
Symptoms of a Failing Blower Motor Resistor in a Durango
When the blower motor resistor in your Dodge Durango starts to fail, the signs are usually obvious. The most common problem is having your fan only work on the highest setting. This is a classic sign that the resistor has burned out. You might also experience the fan not working on any speed, changing speeds on its own, or you may smell a distinct burning plastic odor coming from your vents. That burning smell is a serious warning sign that the resistor and its wiring connector are overheating and melting, which is a common issue on these trucks.
Generation Gap: A Critical Detail for 1998-2009 Durangos
The 1998-2009 Dodge Durango covers two different generations, and the blower motor resistor is in a different place depending on the year.
- First Generation (1998-2003): For most of these years, the resistor is located under the passenger side dashboard and is relatively easy to access with a couple of screws. However, some very early models (around 1998-1999) may have the resistor located in a much more difficult spot under the cowl near the windshield wipers. It is essential to physically look under your passenger side dash first before ordering a part.
- Second Generation (2004-2009): The resistor is located under the passenger side dashboard, near the blower motor itself. It is held in by a few screws and is considered an easy replacement.
Choosing the Right Aftermarket Resistor
Not all aftermarket parts are created equal. For a part like this that handles a lot of electrical current and heat, choosing a quality brand can prevent you from having to do the job twice.
Tier 1: Professional Grade
Standard Ignition (SMP): Often considered a top-tier aftermarket brand by professional mechanics. They use high-quality ceramic and copper components to ensure the resistance values are accurate and the part lasts. If you want to fix it once and be done, this is a solid choice.
Tier 2: DIY Favorites
Dorman: Dorman is well-known for making replacement parts that are widely available. They often sell kits that include a new wiring harness (pigtail), which is highly recommended for this repair since the original connector often melts. The quality is generally good for DIY use.
Four Seasons: A reputable brand in the HVAC parts world. User reviews suggest their parts are often a direct match to the original design and work well.
Tier 3: Value Options
Holstein, Global Parts, True Tech: These brands offer a more budget-friendly price point. While they are built to function like the original, there is less long-term data from professional and owner forums about their durability compared to the other tiers. Holstein marketing states they use high-quality materials.
Pro Tip: The Real Reason Your Resistor Failed
The resistor is usually not the root cause of the problem; it's a symptom. The real culprit is almost always an old, worn-out blower motor. As the motor ages, it gets harder to spin and draws more electrical current (amps) than it should. This extra current overloads the resistor and its wiring, causing them to overheat, melt, and fail. If you only replace the resistor, the old motor will likely burn out the new one in a short time. For a permanent repair, you must replace the blower motor, the resistor, and the wiring connector (pigtail) all at the same time.
Cost of Replacing a Durango Blower Motor Resistor
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Resistor | $18 - $87 |
| New OEM Mopar Resistor | $75 - $150 |
| Shop Labor | $100 - $185 |
| Complete Job (Aftermarket Parts + Labor) | $150 - $350+ |
Costs are estimates and can vary by location and which parts are replaced (resistor only vs. resistor, motor, and pigtail).
Frequently Asked Questions
Why does my fan only work on high?
Because the 'high' setting sends power directly to the fan motor, bypassing the resistor completely. All other lower speeds have to pass through the resistor. When the resistor's internal circuits burn out, only the direct 'high' connection still works.
Is it a fire hazard if I don't fix it?
Yes, it can be. The burning smell many owners report is the wiring connector and resistor melting from excessive heat. There are many documented cases in owner forums of the melted plastic dripping onto the floor mat and nearly starting a fire. If you smell burning plastic, stop using the fan and get it inspected immediately.
Do I really need to replace the blower motor too?
Yes, it is highly recommended by experienced mechanics. The old motor is what caused the resistor to fail in the first place by drawing too much power. Not replacing the motor will almost certainly cause your new resistor to fail prematurely.
Is there a recall for the blower motor resistor on my Durango?
As of early 2026, there are no active, specific recalls from Dodge for the blower motor resistor or its wiring on the 1998-2009 Durango models. However, the issue of melting connectors is a very widely known and documented problem among owners.
Technical Specifications
OEM Part Numbers: 5061575AA 4885635AC 5174618AA 5017124AC
