2011-2014 Dodge Challenger Seat Heater Module: Why Your Heated Seats Are Dead

Symptoms of a Failing Seat Heater Control Module

When the seat heater module in a 2011-2014 Dodge Challenger begins to fail, the symptoms are usually straightforward. Because this single module, located under the driver's seat, controls both front heated seats, a failure can affect one or both seats depending on what went wrong internally.

• Heated Seat Button Lights Up, Then Turns Off: This is one of the most common symptoms. You press the button, the indicator light comes on for a few seconds, and then it shuts off. This typically means the module has performed a self-test and detected a fault in the circuit (like a broken heating element wire or an internal short) and has cut power as a safety precaution.
• No Heat from Either Front Seat: If both heated seats are completely dead and the fuse is good, the module itself is a primary suspect. This points to a total failure of the unit or a loss of its main power or ground connection.
• Only One Seat Heats: The module has separate internal circuits to control the driver and passenger seats. It's possible for one of these circuits to fail, resulting in one functional heated seat and one that doesn't work at all.
• Intermittent Operation: The seats may work sometimes and not others. This can be caused by failing solder joints or corrosion on the module's circuit board or connector pins, leading to a poor connection that is affected by temperature or vibration.
• Seats Stuck on High Heat: A less common symptom is a failure where the module's internal relay sticks in the 'on' position, causing a seat to heat continuously whenever the car is on. This can be uncomfortable and is a potential hazard. If this happens, it's best to pull the fuse for the heated seats until the module can be replaced.

Associated OBD-II trouble codes are typically in the 'B' (Body) category. While a basic code reader may not see them, a more advanced scan tool might find codes such as:

• B2181: Heated Seat Module Power Supply Low
• B2182: Heated Seat Module Power Supply High
• B1092 / B1094: Front Left Seat Heater Control Circuit Low / Open
• B1096 / B1098: Front Right Seat Heater Control Circuit Low / Open

Buying a Used Seat Heater Control Module

Since new aftermarket modules for this specific application are not readily available, a quality used OEM module is often the best and most cost-effective solution. Here’s what to look for:

• Match the Part Number Exactly: This is the most important rule. The part number is printed clearly on the module's label. While there are several compatible part numbers due to revisions, the safest bet is to match the number on your original part. Known part numbers are 68080593AB, 68080593AC, 68080593AD, and 68080593AE. The later letters (like AE) represent newer revisions and will replace earlier versions (like AD).
• Physical Inspection: When buying a used module, inspect the connector pins carefully. Look for any signs of green or white crusty corrosion, which indicates moisture damage. Check the plastic casing for cracks or any signs of melting or heat discoloration. Do not buy a module that shows any evidence of water or heat damage.
• Source and Mileage: Whenever possible, choose a part from a vehicle with lower mileage and from a dry climate to reduce the risk of corrosion and electronic fatigue.
• Why Used OEM is a Good Choice: For an electronic part like this, a used OEM module that is known to be plug-and-play is often a safer choice than a non-existent or questionable aftermarket alternative. The original Mopar part was designed to integrate perfectly with the Challenger's wiring and CAN bus communication system, ensuring it works as intended without causing other electrical gremlins.

Known Issues, Recalls, and TSBs

There are no specific recalls or Technical Service Bulletins (TSBs) issued by Dodge for the failure of the seat heater control module on 2011-2014 Challengers. While other recalls exist for this vehicle generation, such as for a failing alternator (NHTSA ID: 14V-634) and airbags, none directly address the heated seat system. The failures seen are typically due to normal component aging, moisture intrusion under the seat, or breaks in the seat's internal heating element wires.

Replacement and Programming Information

Is Programming Required?

No. The 2011-2014 Dodge Challenger Seat Heater Control Module is a plug-and-play part. You do not need to take the vehicle to a dealer for programming or flashing after installation. As long as you replace it with a compatible OEM part number, the system will function correctly immediately after installation. The module does not have an anti-theft link and is not tied to the vehicle's VIN.

Replacement Walkthrough

The module is located under the driver's seat, attached to the seat frame. Accessing it requires unbolting the driver's seat from the floor.

1. Disconnect the Battery: Before working on any electronic component, disconnect the negative terminal of the battery located in the trunk.
2. Unbolt the Driver's Seat: The seat is held to the floor by four bolts at each corner of the seat rails. Slide the seat forward to access the rear bolts and backward to access the front bolts.
3. Tilt the Seat: With the bolts removed, carefully tilt the entire seat assembly backward to gain access to the wiring and modules underneath. Be careful not to strain the main wiring harness connected to the seat.
4. Locate and Disconnect the Module: The seat heater module is a small black plastic box. Disconnect the electrical connectors attached to it.
5. Remove the Old Module: The module is typically held to the seat frame with a couple of small screws or clips. Remove them and take out the old module.
6. Install the New Module: Mount the replacement module in the same location and reconnect the electrical connectors.
7. Reassemble and Test: Bolt the seat back into place, reconnect the battery, and test the function of both heated seats on all settings.
