A Guide to the Engine Cooling Fan Module for the 2011-2019 Jeep Grand Cherokee
If your Grand Cherokee is overheating at stoplights, the engine cooling fan module could be the culprit.
- Engine overheating at idle is the #1 symptom of a bad cooling fan.
- Always check the fan fuses and relays in the under-hood fuse box before replacing the entire assembly.
- The fan module is typically sold as part of the complete fan assembly (motor, blades, and shroud).
- Aftermarket parts are cheaper but may require wiring modifications; Mopar offers a guaranteed fit but costs more.
Is Your Grand Cherokee's Cooling Fan Failing?
The engine cooling fan is critical for your 2011-2019 Jeep Grand Cherokee, especially in stop-and-go traffic or on hot days. When it fails, the engine can quickly overheat, leading to serious damage. The cooling fan module, which is usually built into the fan assembly, is often the point of failure. Understanding the signs of a bad module can help you diagnose the problem before it becomes a costly repair.
Common Symptoms of a Bad Fan Module
Watch for these clear signs that your fan module or assembly is having issues:
- Engine Temperature Rises at Idle: The most common symptom. If the temperature gauge climbs when you're stopped at a light but returns to normal when you start moving, your fan isn't working.
- A/C Blows Warm Air: The fan pulls air across the A/C condenser. If the fan is off, your A/C system can't get rid of heat and won't be able to cool the cabin.
- Fan Stays On After Engine is Off: A faulty module can cause the fan to run continuously, even after you've parked and locked your Jeep. This will drain your battery.
- Fan Doesn't Turn On at All: If you let the engine idle and get up to temperature (or turn on the A/C), the fan should kick on. If it stays still, the module, motor, or a fuse could be bad.
Check Fuses and Relays First
Before buying a whole new fan assembly, always check the simple things first. Your Grand Cherokee has fuses and relays for the cooling fan located in the power module under the hood. A blown fuse or a bad relay is a much cheaper and easier fix.

When it's time to replace the fan assembly, you have two main choices: OEM (Mopar) or an aftermarket brand.
- Mopar (OEM): This is the original part your Jeep came with. It guarantees a perfect fit, correct wiring connectors, and factory-level quality. However, it is the most expensive option.
- Aftermarket: Brands like Dorman or TRQ offer a more affordable alternative. While they can save you a significant amount of money, be aware of potential issues. Some owners report that aftermarket parts may have slightly different wiring connectors that require splicing, and their long-term durability can sometimes be less than the Mopar part.
If you choose an aftermarket part, buy from a reputable seller with a good warranty. Read reviews to see if other Grand Cherokee owners have had issues with wiring or fitment for that specific brand.
Estimated Replacement Costs
Prices can vary based on your specific engine and the supplier.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Mopar) Assembly | $350 - $650 |
| New Aftermarket Assembly | $150 - $350 |
| Shop Labor | $150 - $225 |
Frequently Asked Questions
Is there a recall on the cooling fan module?
As of early 2026, there are no widespread safety recalls specifically for the engine cooling fan module on the 2011-2019 Jeep Grand Cherokee. There was a recall for older models (2000-2002) and for the HVAC blower motor on newer models, but these do not apply to the engine cooling fan for this year range.
Can I replace the fan module myself?
Yes, this is a DIY-friendly job for someone with basic mechanical skills. The process involves removing the top engine cover and air intake ducting to access the fan assembly, which is held in by clips. It typically requires common hand tools and takes about 1-2 hours.
🎬 Watch this step-by-step guide to replacing the full fan assembly.Is the fan module the same as the fan relay?
No. The fan relays are separate, smaller electrical switches located in the under-hood fuse box. The fan module is a more complex electronic controller that is usually integrated directly into the fan shroud or motor assembly itself. Always check the relays first, as they are a common and inexpensive failure point.

This is a classic sign of a failed fan module. The internal electronics can short in a way that keeps the fan powered on constantly, which will drain your battery. It is not normal for the fan to run for more than a minute after shutdown, if at all.

The cooling fan module is an integrated electronic controller for the electric radiator fan. It receives a pulse-width modulated (PWM) signal from the ECU to vary fan speed based on engine temperature and A/C demand. The entire unit is typically replaced as a single assembly including the fan, motor, and shroud.
