2015 Cherokee & 200 Seat Heater Module Failure: Programming and Replacement Guide

Symptoms of a Failing Seat Heater Control Module

When the seat heater module in your 2015 Jeep Cherokee or Chrysler 200 begins to fail, the symptoms are usually straightforward. Because this single module controls multiple functions, you may notice several issues at once.

• Heated or Ventilated Seats Are Completely Inoperative: The most common symptom is when neither the driver nor passenger heated or ventilated seats work. The indicator light on the touchscreen may light up briefly and then turn off, or it may not respond at all.
• Heated Steering Wheel Does Not Work: Since this module also controls the heated steering wheel, a complete failure will often disable this feature as well.
• Intermittent Operation: The seats or steering wheel may work one day and not the next. This can be caused by failing internal components or a poor electrical connection at the module.
• One Seat Works, The Other Doesn't: The module has separate channels for the driver and passenger seats. It's possible for one channel to fail, leaving one seat functional while the other is dead.
• Features Stuck On: In rare cases, a switch or internal relay can fail in the 'on' position, causing a seat heater to stay on continuously. This can be a safety hazard and should be addressed immediately.

Before replacing the module, always check the fuses first. In the 2015 Jeep Cherokee, the primary fuse for the front heated seats is F63 (a 25A fuse) located in the main fuse box under the hood. Fuse F64 may be related to the heated steering wheel on some models. A simple blown fuse can mimic the symptoms of a failed module.

Associated OBD-II Codes

A professional scan tool that can read Body Control Module (BCM) codes may reveal Diagnostic Trouble Codes (DTCs). A generic code reader often won't see these. Common codes include:

• Communication Codes (U-codes): A loss of communication with the Heated Seat Module (HSM) is a strong indicator of a failed module or a wiring issue.
• B-codes: Body codes like B1925, B2170, B2425, or B2430 can indicate loose terminal connections or faults within the module itself.

Known Issues, TSBs, and Recalls

While there are no specific recalls for this module, there is a highly relevant Technical Service Bulletin (TSB) for the 2015 Chrysler 200 that may also apply to the Jeep Cherokee due to the shared platform.

TSB 08-065-15: Lumpy Seat Cushion (2015 Chrysler 200)

Some owners of 2015 Chrysler 200 models built on or before September 29, 2014, reported feeling a hard or lumpy spot in the seat bottom cushion. This was caused by a failure of the heating element pad. The official repair procedure involves replacing not only the seat cushion foam and the heating pad itself, but also the Seat Heater Control Module. After replacement, the vehicle requires a "PROXI Configuration Alignment" to make the new module work with the car. This indicates that a failing heating element can potentially damage the control module, or that an updated module was part of the complete fix.

Programming and Calibration Requirements

This programming process is called PROXI Configuration Alignment (or just PROXI alignment). It's a procedure that synchronizes the vehicle's master configuration list, stored in the Body Control Module (BCM), with all the other individual modules in the car, including the new seat heater module. This tells the car's network that the module is present and what features it is expected to control.

Who Can Program the Module?

• FCA Dealerships: Any Chrysler, Dodge, Jeep, or Ram dealer can perform a PROXI alignment using their proprietary wiTECH diagnostic tool. This service is often part of a one-hour diagnostic fee.
• Independent Shops: Many independent repair shops that specialize in Chrysler products or have high-end scan tools (like some Snap-on models) can perform a PROXI alignment.
• DIY Mechanics: Advanced DIYers can perform this procedure themselves. Software like Appcar DiagFCA and AlfaOBD, when paired with a compatible OBD2 adapter, can successfully run the PROXI alignment routine on the 2015 Jeep Cherokee (KL) and Chrysler 200 (UF). This is often the most cost-effective option if you plan to do more diagnostics or customizations in the future.

Replacement Guide

Physically replacing the module is relatively easy. The main challenge is the programming required after installation.

• Difficulty: 2/5 (physical swap), 4/5 (including programming)
• Tools Needed: Socket set, trim removal tools, compatible scan tool for PROXI alignment.
• Location: The Seat Heater Control Module is located under the front passenger seat in both the 2015 Jeep Cherokee and Chrysler 200.

Step-by-Step Overview

1. Disconnect the Battery: Before working on any electronic module, disconnect the negative battery terminal to prevent electrical shorts.
2. Access the Module: You may need to unbolt the front passenger seat and tilt it back to gain clear access to the wiring and module underneath.
3. Disconnect and Remove: The module is held in place by a few small bolts or clips. Carefully disconnect the electrical connectors (there may be several) and remove the old module.
4. Install the New Module: Bolt the new module in place and securely reconnect all electrical connectors.
5. Reassemble and Reconnect: Bolt the seat back into place and reconnect the negative battery terminal.
6. Perform PROXI Alignment: This is the final, mandatory step. Use a dealer's wiTECH tool, a capable independent shop scanner, or a DIY tool like AlfaOBD or Appcar DiagFCA to run the "PROXI Configuration Alignment" procedure. This will sync the new module with your vehicle. After the alignment, clear any DTCs that may have been set during the process.

Buying a Used Seat Heater Control Module

A used OEM module is an excellent, cost-effective alternative to a new part, especially since new aftermarket options are not widely available for this specific component. Here’s what to look for:

• Match Vehicle Options: This is the most critical step. The module is specific to the options on the vehicle. The initial prompt noted the module is for vehicles with heated front seats, ventilated front seats, AND a heated steering wheel. TSB 08-065-15 confirms different modules exist for cars with and without the heated steering wheel. You must buy a module from a donor vehicle with the exact same climate seat/steering wheel options as your car.
• Verify Part Numbers: Check the part number on your original module and match it as closely as possible. Several part numbers may work. For example, 68223680AD is listed for both the 2015 Cherokee and 200. Part number 68105045AE was superseded by several newer numbers, including 68105045AF and 68465229AA. A part from a newer vehicle in the same generation may work, but always prioritize matching the options first.
• Physical Inspection: When you receive the used part, inspect the connectors for any signs of corrosion, bent pins, or water damage. The case should be free of cracks or signs of being opened.
• Programming is Still Required: Remember, even a used OEM module must be programmed to your vehicle with a PROXI alignment. Factor in the cost of this procedure when buying the part.
