2024 Jeep Wrangler & Gladiator Climate Seat Module: A Guide to Failures and Programming
Here's what to know about diagnosing, replacing, and programming the new-for-2024 heated and ventilated seat module in your Jeep.
- This module controls both heating and the new-for-2024 ventilation feature in Jeep Wranglers and Gladiators.
- A replacement module, whether new or used, will almost certainly require programming by a dealer or specialist with wiTECH software to function.
- When buying used, get the latest part revision possible (e.g., 'AC' suffix) and budget for programming costs.
- Symptoms are straightforward: heat or ventilation stops working, either completely or intermittently, for one or both seats.
Symptoms of a Failing Climate Controlled Seat Module
When the climate seat module begins to fail, it typically results in the loss of heating, ventilation, or both. Because it's an electronic component, failures can be sudden and complete, or intermittent. The 2024 Wrangler and Gladiator are new models, so widespread issues are not yet documented, but here are the most likely symptoms based on module failures in similar vehicles.
- Heated or Ventilated Seats Don't Turn On: The most common symptom is a complete lack of function. You press the button on the Uconnect screen, the icon may or may not light up, but you feel no temperature change or airflow.
- One Function Works, The Other Doesn't: The module has separate circuits for heating and ventilation. It's possible for the heating to work while ventilation does not, or vice-versa.
- Intermittent Operation: The seats may work sometimes and not others. This can be caused by a failing component within the module, a loose connection, or temperature-related solder joint failures.
- Stuck on High or Low Setting: A faulty module could fail to regulate the temperature or fan speed, causing the seat to be stuck on one setting regardless of your selection.
- Only One Seat Works: While each front seat has its own heating and ventilation hardware, they are controlled by a central module. However, a failure in one of the output channels could cause only the driver or passenger seat to stop working.
A technician with a capable scan tool may find Diagnostic Trouble Codes (DTCs) stored. While codes for the module itself are not commonly published, related codes may point to the problem. A Technical Service Bulletin for other Jeep models identified the following codes related to open circuits in the seat heater elements, which could indicate a problem with the element, its wiring, or the module itself.
- B1E99-13: (Left Side Back) - Front Left Heater Control 1-Circuit Open
- B1E9A-13: (Right Side Back) - Front Right Heater Control 1-Circuit Open
- B1F10-13: (Left Side Cushion) - Front Left Heater Control 2-Circuit Open
- B1F11-13: (Right Side Cushion) - Front Right Heater Control 2-Circuit Open
Pro Tip: Don't confuse ventilated seats with air-conditioned seats. The system in the Wrangler and Gladiator uses fans to pull cabin air and circulate it through the seat perforations. It does not use refrigerated air from the A/C system. Its effectiveness is dependent on the ambient temperature inside the vehicle.
Programming and Installation Requirements
This is the most critical factor when replacing the Climate Controlled Seat Module in a 2024 Jeep Wrangler or Gladiator.
A replacement module will likely require programming to function correctly. While no specific TSB for the 2024 models confirms this yet, all modern Jeeps use a complex CAN bus network where new modules must be introduced to the vehicle's central computer. This process is often called a "Proxy Configuration Alignment."
Failure to program a new or used module can result in it not being recognized by the vehicle, leading to a complete lack of function. This is not a simple plug-and-play part.
- Dealer Programming: A Jeep dealership is the most reliable option for programming. They use a proprietary tool called wiTECH to perform the proxy alignment and ensure the module communicates correctly with the Body Control Module (BCM) and Uconnect system.
- Independent Shops: Some high-end independent repair shops may have aftermarket scan tools with the capability to perform this programming, but you must confirm with them beforehand.
- DIY Programmers: Devices like the OBD Genie are available for adding features to Jeeps, but compatibility with this specific module replacement is not guaranteed and often requires a security gateway bypass module for any 2018+ vehicle.
Warning: When purchasing a used module, you MUST factor in the potential cost of a visit to a dealer or specialist for programming. Assume it will not work correctly by simply swapping the part.
Buying a Used Climate Controlled Seat Module
Buying a used OEM module can be a smart way to save money, especially since aftermarket options for this new part are not available. Here’s what to look for:
- Match the Part Number Series: The known OEM part numbers are 68631168AA, 68631168AB, and 68631168AC. The letters at the end signify revisions. Always try to buy the newest revision available (currently 68631168AC), as it may contain hardware or firmware improvements over older versions. Any of these should be compatible, but the latest version is the safest bet.
- Physical Inspection: Check the module for any signs of physical damage, especially to the connectors. The pins should be straight and free of corrosion. Avoid any parts that show signs of water damage or have been in a fire.
- Source Vehicle Information: If possible, get the VIN of the vehicle the part came from. This can help verify compatibility and, in some cases, is needed for programming. Low-mileage donor vehicles are always preferable.
- Reputable Seller: Purchase from a trusted auto recycler that offers a warranty. This gives you protection in case the module is dead on arrival, even before you attempt to have it programmed.
Cost to Replace Climate Controlled Seat Module
Costs can vary by region and supplier, but here is a general estimate for the 2024 Jeep Wrangler and Gladiator.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Mopar) | $75 - $120 |
| New Aftermarket | Not Yet Available |
| Used OEM | $40 - $80 |
| Shop Labor (Replacement Only) | $50 - $100 (0.5-1.0 hours) |
| Shop Labor (Programming) | $100 - $200 (Typically 1.0 hour minimum diagnostic fee) |
Frequently Asked Questions (FAQ)
Do I absolutely need to program a replacement climate seat module?
Yes, it is almost certain. On modern vehicles like the 2024 Wrangler and Gladiator, new electronic modules need to be registered with the vehicle's network to function. Expect to visit a dealer or a well-equipped independent shop with Jeep-specific software to have the module programmed.
What's the difference between part numbers 68631168AA, 68631168AB, and 68631168AC?
These numbers represent different revisions of the same part. The 'AC' version is the newest and supersedes the 'AA' and 'AB' versions. While any should work, it is always best practice to install the latest available revision to benefit from any potential fixes or improvements.
Can I install this module myself to save money?
Physically replacing the module is likely straightforward for someone with basic DIY skills. It is often located under one of the front seats, accessible by removing a few bolts. However, the part will not function until it is electronically programmed to the vehicle, which requires specialized tools. You can do the physical swap, but you will still need to drive the vehicle to a shop for the final, critical step.
Can I use this module to add climate seats to my base model Wrangler/Gladiator?
No. This is not a simple upgrade. A vehicle without factory climate seats is missing the ventilation fans, heating elements, perforated leather/cloth, and the necessary wiring harnesses and Uconnect software. This module is only for repairing a vehicle that was originally equipped with climate-controlled seats.
