2001-2007 Dodge Caravan HVAC Blower Motor Resistor Guide
If your Caravan's fan only works on the high setting, this simple part is almost always the reason why.
- The most common symptom of failure is the fan only working on the highest speed setting.
- Replacement is very easy and located behind the glove box, requiring only an 8mm socket or wrench.
- Always inspect the wiring connector for melting; if damaged, you must also replace the blower motor and connector pigtail for a lasting repair.
- Quality aftermarket brands like Dorman or Standard are reliable and cost-effective alternatives to the OEM part for this specific repair.
Symptoms of a Bad Blower Motor Resistor in a Dodge Caravan
For the 2001-2007 Dodge Caravan, a failing blower motor resistor has very specific and common symptoms. The most frequent issue you'll notice is that the fan only works on the highest setting. This happens because the high setting sends full power directly to the blower motor, bypassing the resistor. The lower speeds (1, 2, 3, etc.) must go through the resistor, and when it fails, those speeds stop working.
- Fan only works on high: This is the classic sign of a failed resistor.
- Some fan speeds don't work: You might lose one or two speeds while others still function.
- No fan at any speed: While less common, a complete failure of the resistor or its connector can kill all power to the blower motor.
- Burning smell from vents: An overheating resistor or melting electrical connector can produce a distinct plastic or electrical burning smell. This is a serious symptom that requires immediate attention.
Pro-Tip: Check the Blower Motor and Connector
Often, the blower motor resistor doesn't just fail on its own. The root cause is frequently an old, failing blower motor that is drawing too much electrical current. This extra current overheats and burns out the resistor. When you pull out the old resistor, inspect its electrical connector and the wiring harness for any signs of melting, browning, or corrosion. If you see any heat damage, it is critical to replace the blower motor and the resistor's wiring connector (pigtail) 🎬 See how to replace both the fan and the resistor. along with the resistor itself. Failing to do so will cause the new resistor to burn out very quickly.
Choosing the Right Aftermarket Resistor
For a simple electronic part like this, you don't necessarily need to buy the expensive OEM Mopar part. Many aftermarket brands offer quality replacements that meet or exceed original specifications. They are often divided into different tiers based on quality and price.
- Premium Aftermarket (e.g., Dorman, Standard Motor Products, Four Seasons): These are well-known brands that often engineer improvements over the original design. Dorman, for example, is a very common and trusted replacement for this part and is sometimes available in a kit with the new wiring harness you might need.
- Standard Aftermarket (e.g., Crown Automotive, URO Parts, Holstein): These brands provide a direct replacement that functions like the original. They are a reliable and cost-effective choice for this repair.
- Value Brands (e.g., Global Parts, True Tech): These are typically the most affordable options. While they can be a good budget choice, they may not have the same longevity or rigorous testing as premium brands.
Important: Your 2001-2007 Caravan uses a different resistor for manual and automatic climate control systems. Ensure you are buying the correct part for your specific vehicle. The replacement is very easy and accessible behind the glove box.

Frequently Asked Questions
Is it hard to replace the blower motor resistor on a 2001-2007 Caravan?
No, it is a very easy repair that most DIYers can do in under 20 minutes. You just need to open and lower the glove box, unplug two electrical connectors, and remove two 8mm screws. The resistor pulls straight out of the HVAC housing.
Where is the blower motor resistor located?
It is located behind the glove compartment, plugged into the main HVAC ductwork. To access it, you open the glove box, press in the sides to let it drop down completely, and you will see the resistor with its two wiring connectors.
Why did my new resistor fail after only a few weeks?
This is almost always caused by an old blower motor drawing too much power, which overheats the new resistor. If your original resistor's connector showed any signs of melting or discoloration, you must replace the blower motor and the wiring pigtail connector to fix the problem permanently.
🎬 Watch a detailed guide on replacing the blower motor and resistor.Are there any recalls for the blower motor resistor on these vans?
Searches found an older recall (91V-004) for much earlier model years related to water intrusion causing resistor failure and fire risk, but this does not apply to the 2001-2007 generation. There are no specific recalls for the blower motor resistor on the 2001-2007 Dodge Caravan according to NHTSA searches.
