Chrysler Pacifica HVAC Blower Motor Resistor Guide (2004-2009)
Is your Pacifica's fan stuck on one speed or not working at all? Here's what you need to know.
- The most common symptom of failure is the fan only working on the highest speed setting.
- Replacement is very easy, located behind the glove box, and requires only an 8mm socket.
- If the electrical connector is melted, replace it and strongly consider replacing the blower motor at the same time.
- All 2004-2009 Pacificas have Automatic Temperature Control, so ensure the part is listed as compatible.
Is Your Pacifica's Fan Acting Up?
If your 2004-2009 Chrysler Pacifica's climate control fan has a mind of its own, a faulty blower motor resistor is the most likely culprit. This is a very common issue on these vehicles. The most classic symptom is the fan only working on the highest setting. This happens because the high setting bypasses the resistor entirely, sending full power directly to the blower motor. Other signs include certain speeds not working, the fan not working at all, or intermittent operation.

The 2004-2009 Pacifica came standard with Automatic Temperature Control (ATC). For this system, the part is technically a "Blower Motor Control Module," not a simple resistor, but it performs the same job of controlling fan speed. The terms are often used interchangeably by owners and even some parts stores, but it's crucial to get the correct part for your vehicle's ATC system.
Choosing the Right Aftermarket Part
When your blower motor resistor fails, you have a choice between the original Mopar part and several aftermarket brands. For a vehicle of this age, an aftermarket part offers the best value and is a perfectly reliable solution.
- Premium Aftermarket (e.g., Standard Ignition, Four Seasons, Dorman): Brands like Dorman, Standard, and Four Seasons are well-known in the aftermarket world. They design their parts to match the original's fit and function and are a dependable choice for this repair. They often offer a good balance of quality and price.
- Value-Oriented Brands (e.g., URO Parts, Global Parts, True Tech): These brands can offer significant savings. For a simple, common-to-fail part like a blower resistor, these can be a smart choice, especially for a DIY repair where labor cost isn't a factor.
Pro Tip: If the old resistor's electrical connector looks melted or burnt, you should replace the connector pigtail at the same time. More importantly, a melted connector is a strong sign that the blower motor itself is old, drawing too much power, and will likely cause your new resistor to fail prematurely. Consider replacing the blower motor as well if you see signs of overheating.
Cost of Replacing the Blower Motor Resistor
| Part Type | Estimated Cost |

| New OEM (Mopar) Resistor | $100 - $175+ |
| Shop Labor Cost | $50 - $120 |
Frequently Asked Questions
Where is the blower motor resistor located on a 2004-2009 Pacifica?
The blower motor resistor is located behind the glove box on the passenger side. You'll need to empty the glove box, press in the sides to release the stops, and let it hang down to access the area behind it. The resistor is mounted in the HVAC housing and held in by two 8mm screws.
🎬 See a step-by-step guide on replacing the blower motor resistor.Is replacing the blower motor resistor a DIY job?
Yes, this is a great DIY job for beginners. The only tool you typically need is an 8mm socket with a small ratchet and extension. The entire process usually takes less than 30 minutes. Simply disconnect the battery, lower the glove box, unplug the two electrical connectors, remove two screws, swap the part, and reassemble.
🎬 Follow this visual walkthrough to replace your blower motor module.Why did my new blower motor resistor fail after only a few months?
This almost always means the blower motor itself is failing. As a blower motor ages, it has to work harder and draws more electrical current. This extra current overloads the new resistor, causing it to burn out quickly. If you're replacing the resistor a second time, you should replace the blower motor too.
Are there any recalls for the Pacifica blower motor resistor?
No, there are no specific recalls for the blower motor resistor on the 2004-2009 Chrysler Pacifica. Searches on the NHTSA database show recalls for newer Pacifica models related to battery packs and other issues, but not for this specific part in this year range.
