2023-2025 Civic Type R & Integra Type S A/C Control Module: Diagnosis and Replacement Guide

Vehicle Fitment and Part Identification

This guide specifically covers the dual-zone automatic temperature control module used in the following high-performance models:

• 2023-2025 Honda Civic Type R
• 2024-2025 Acura Integra Type S

Known OEM Part Numbers

The primary OEM part number for this module is 79600-T60-A51. You may also see it listed as 79600-T60-A510 or 79600T60A51. This part is used by both Honda for the Civic Type R and Acura for the Integra Type S, confirming they are interchangeable.

Symptoms of a Failing A/C Control Module

A faulty climate control module can cause a wide range of confusing symptoms. Because it's the central computer for the HVAC system, its failure can mimic problems with other components like the blower motor or blend door actuators. Here are the most common signs of a bad module:

• Inconsistent or Incorrect Temperatures: The system blows hot air when you want cold, or vice-versa. The temperature may fluctuate wildly without you touching the controls.
• Blower Fan Issues: The fan may be stuck on one speed (often high), refuse to turn on at all, or not respond to changes you make with the fan speed control.
• Air Blows from Wrong Vents: You select the dashboard vents, but air only comes out at the floor or defroster. The system gets stuck in one mode and won't change.
• Unresponsive Controls or Blank Display: The buttons or knobs stop working, or the entire climate control panel goes dark and becomes unresponsive.
• A/C Compressor Won't Engage: Even with a full refrigerant charge, the module may fail to send the signal to turn on the A/C compressor.

Known Issues, TSBs, and Recalls

As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Honda or Acura for failures of the A/C automatic temperature control module in the 2023-2025 Civic Type R or 2024-2025 Integra Type S. The vehicles are still relatively new, so widespread issues have not yet been identified.

However, there is a TSB for some 2022-2023 Civic models where the A/C does not blow cold due to an oil leak from the condenser. If you are experiencing a lack of cold air, it is wise to have the condenser inspected for leaks before suspecting the control module.

Programming and Initialization Requirements

This is the most critical question when replacing this electronic module. The answer depends on whether you are using a new or used part.

• New OEM Modules: A brand new module from Honda or Acura generally comes pre-programmed from the factory. This means it does not require complex VIN programming with a dealer tool. However, it will likely require an "initialization" or "calibration" procedure after installation. This allows the module to learn the positions of the blend doors and actuators in your specific vehicle. This can sometimes be done with a simple procedure like disconnecting the battery for 10 minutes, reconnecting it, and letting the system run for several minutes without touching the controls.
• Used OEM Modules: A used module from a salvage vehicle may or may not be plug-and-play. While it is not tied to the vehicle's immobilizer system, it may retain settings from the donor car. If you experience issues after installing a used module, it may need to be updated or reprogrammed by a technician with access to Honda's J2534 software or by a remote programming service.

Buying a Used A/C Automatic Temperature Control Module

Buying a used OEM module can be a smart way to save money, as aftermarket options for these new vehicles are not yet available. A used OEM part is often more reliable than a cheap aftermarket alternative. Here’s what to look for:

• Verify the Part Number: Your number one priority is to match the part number exactly. Ensure the seller lists 79600-T60-A51. Do not buy a module from a standard Civic or Integra.
• Inspect for Physical Damage: Check the photos for any cracks in the plastic housing, bent pins on the electrical connectors, or signs of water intrusion or corrosion.
• Check the Source Vehicle: If possible, find out the mileage of the donor vehicle. A module from a low-mileage car is always preferable.
• Seller's Return Policy: Buy from a reputable seller with a good return policy. Since there's a small chance of a compatibility issue that requires programming, you want the option to return the part if it doesn't work correctly after a simple initialization.

Cost Comparison

Replacing the A/C control module can vary in cost depending on the route you take. Labor costs are generally low, as the module is typically accessible after removing some dash trim.
