Signs of a Failing Fan Module
A bad cooling fan module on a 1996-2007 Dodge Caravan has very specific symptoms. The most common is when the cooling fans keep running after you've turned the van off, which will drain your battery. Another classic sign is the engine temperature climbing while idling or in stop-and-go traffic, but cooling down once you're moving at speed. You might also notice your air conditioning isn't blowing cold air when you're stopped. In some cases, the fans won't turn on at all, leading to serious overheating. A check engine light with code P0480, which points to a fan control circuit problem 🎬 Watch: How to repair cooling fans and fix code P0480., is also a strong indicator.
Don't Ignore Symptoms
Driving with a faulty fan module can lead to engine overheating. This can cause severe and expensive damage, like a warped cylinder head or a blown head gasket. If your temperature gauge is in the red, pull over immediately.
Choosing the Right Aftermarket Module
For an older vehicle like the 1996-2007 Caravan, a quality aftermarket fan module is a smart and economical choice. The original factory modules are known to fail, and aftermarket brands often provide reliable replacements. Here's a look at the available brands:
- Standard Ignition (SMP): Often considered a top-tier aftermarket brand, Standard produces parts that meet or exceed original specifications. Their modules are known for quality construction with high-quality housings and contacts to withstand under-hood heat.
- Gates: While famous for belts and hoses, Gates also manufactures electronic components like fan modules. They aim for OE-performance and often engineer improvements into parts with high failure rates.
- Rostra Powertrain: Rostra is a well-established name in automotive electronics, providing reliable components for a variety of vehicle systems.
Pro Tip: The fan module for these vans is a solid-state relay, typically mounted to the frame rail under the driver's side, near the air filter housing or front bumper support. Due to its location, it's exposed to road salt and moisture, which contributes to failure. When replacing, applying a bit of dielectric grease to the connector can help prevent future corrosion.

Frequently Asked Questions
Can I replace the fan module myself?

Is there a recall on the fan module for my Caravan?
Searches of the NHTSA database show recalls for cooling fan issues on other, newer Dodge vehicles, but no specific recalls were found for the engine cooling fan module on the 1996-2007 Dodge Caravan. Failures on these older models are typically due to age and wear.
What's the difference between a fan relay and a fan module?
For this specific vehicle, the terms are often used interchangeably. The part is technically a solid-state relay module. Unlike a simple on/off relay, this module allows for variable fan speed control based on the engine's needs, though it functions as the primary relay in the circuit.
Why do my fans run even when the van is off?
This is the most common failure mode for this specific part. The internal electronics of the module fail in the "on" position, creating a closed circuit that continuously sends power to the fans, even without the key in the ignition. This will drain the battery if not addressed.
