⚠️ Drivable, but... — Yes, but you will not have control over your cabin fan speed, which can affect defroster performance in certain weather.
Key Takeaways
  • The most common symptom of failure is the fan only working on the highest speed setting.
  • If the old resistor or its connector is burnt, you should also replace the blower motor to prevent the new resistor from failing quickly.
  • Aftermarket brands like Dorman and Standard Ignition offer OEM-quality alternatives, and kits with a new wiring harness are a smart choice.
  • This is an easy DIY repair located behind the glove box that most owners can complete in under an hour.
The HVAC blower motor resistor is a small electronic part that controls your van's fan speed. When you adjust the fan knob or button, the resistor changes the amount of electrical power going to the blower motor. This allows you to have different fan speeds, from low to high. In the Chrysler Pacifica, this part is often a solid-state electronic module, which allows for more precise, variable speed control rather than just a few set speeds. The highest fan setting usually bypasses the resistor and sends full power directly to the blower motor.

Common Failure Symptoms in the Chrysler Pacifica

When the blower motor resistor starts to fail, your climate control fan will act up. Look for these common signs in your 2017-2025 Pacifica:

  • Fan Only Works on High Speed: This is the most classic symptom. The lower speeds stop working because they rely on the resistor, but the high-speed setting bypasses it.
  • 🎬 Watch: Why your fan only works on high speed
  • Some Fan Speeds Don't Work: You might lose one or two speeds while others still function.
  • No Airflow at All: In some cases, the resistor can fail completely, preventing the fan from working on any speed. Before blaming the resistor, it's a good idea to check the blower motor fuses (F26 for the front, F39 for the rear in the under-hood fuse box).

  • Intermittent Operation: The fan may work sometimes and not others, or cut in and out while you're driving.
  • Burning Smell from Vents: A plastic or electrical burning smell is a serious sign that the resistor or its wiring connector is overheating and melting. You should inspect this immediately.
Warning: If you smell burning plastic, the electrical connector for the resistor may be melting. This is often caused by a failing blower motor drawing too much electricity. Ignoring this can be a fire hazard.

Choosing the Right Aftermarket Part

Quality aftermarket kits, like those from Dorman, often include a new wiring harness pigtail to replace melted original connectors.

You don't need to buy an expensive OEM part from the dealer. Quality aftermarket brands offer reliable performance for your Pacifica, often at a much better price. Here’s how the available brands generally stack up:

  • Premium Aftermarket (OEM-Equivalent Quality): Brands like Standard Ignition (SMP) and Dorman are well-regarded for their quality and engineering. Dorman, in particular, often sells kits that include a new wiring harness. This is extremely useful if your Pacifica's original connector has melted.
  • Standard Aftermarket (Good Value): Brands like Four Seasons, Global Parts (GPD), and Holstein are solid, budget-friendly choices. Four Seasons and GPD are specialists in climate control systems. Holstein focuses on electronic parts and offers a strong warranty. While generally reliable, some user forums mention occasional noise or quality differences with these brands compared to OEM, but many DIYers use them without issue.
Pro Tip: If you find a melted resistor or connector, you should also replace the blower motor. An old, worn-out blower motor pulls too much electrical current, which is what causes the new resistor to overheat and fail prematurely.

Frequently Asked Questions (FAQ)

The location of the blower motor resistor behind the glove box in a Chrysler Pacifica.
The resistor is easily accessible behind the glove box, making it a straightforward DIY project for most Pacifica owners.
Can I replace the blower motor resistor myself?

Yes, this is a very DIY-friendly job. The resistor is usually located behind the glove box and is held in by two screws. The entire process typically takes less than an hour and only requires basic hand tools.

🎬 Watch this step-by-step blower motor resistor replacement guide
Why did my new resistor fail after only a few months?

This almost always happens because the underlying problem was not addressed. The most common cause is an old blower motor that is drawing too much electrical current. This extra load overheats and burns out the new resistor. If you're replacing a resistor, especially a burnt one, it's wise to replace the blower motor at the same time.

Should I also replace the wiring connector?

Always inspect the wiring connector. If it shows any signs of discoloration, melting, or corrosion, you must replace it. Some aftermarket brands like Dorman sell kits that include the resistor and a new connector pigtail for this reason. Splicing in a new connector is critical for a lasting repair.

Are there any recalls for this part on the Pacifica?

As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Chrysler for the blower motor resistor on 2017-2025 Pacifica models. Failures are typically due to normal wear and tear.

Technical Specifications

OEM Part Numbers: 68223049AA 68537999AA 68110616AB 68379071AA

The Chrysler Pacifica uses a solid-state blower motor control module rather than a traditional wire-wound resistor. This allows for variable fan speed control. It is typically located in the HVAC housing behind the glove box and has a multi-pin electrical connector.
