Tools required

Parts

• Climate control module × 1 — Use OEM specification
• Dash panel clips (assorted) × 1 — Replace any broken clips

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key fob from vehicle
3. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge
4. Set steering wheel to center position
5. Ensure transmission is in Park position

Procedure

1. 1

   Remove lower dashboard trim panel
   Using a panel removal tool, carefully pry out the lower dashboard trim panel below the climate control unit. Start from the bottom edge and work around the perimeter. Release the retaining clips by pulling gently outward. Remove the panel completely and set aside.
2. 2

   Remove center console side trim panels
   Remove the left and right side trim panels from the center console area. These snap into place with clips. Use a trim removal tool to release the clips starting from the rear edge of each panel and working forward. Disconnect any electrical connectors for switches if equipped.
3. 3

   Remove climate control bezel
   Locate and remove the decorative bezel surrounding the climate control module and radio. This bezel is held by clips around the perimeter. Insert a panel tool at the bottom edge and carefully work around releasing each clip. Pull the bezel straight out once all clips are released. No screws secure this panel on 2018-2024 Accord models.
4. 4

   Remove climate control mounting screws
   With the bezel removed, locate the four Phillips-head screws securing the climate control module to the dashboard frame. Remove all four screws completely and retain them for reinstallation. The module will now be loose but still connected by wiring harnesses.

5. 5

   Pull module forward and access connectors
   Carefully pull the climate control module straight out from the dashboard opening approximately 3-4 inches. Use a flashlight to illuminate the rear of the module. You will see two main electrical connectors and potentially one smaller connector for ambient lighting.
6. 6

   Disconnect electrical connectors
   Depress the locking tab on each electrical connector while pulling straight back to disconnect. The main connectors have a gray or white sliding lock that must be pushed toward the module before the tab can be released. Disconnect all connectors and remove the old climate control module completely from the vehicle.
7. 7

   Prepare new climate control module
   Unpack the new climate control module and inspect it for any shipping damage. Verify all connector ports are clean and free of debris. Compare the new module to the old one to confirm correct replacement part.
8. 8

   Connect electrical harnesses to new module
   Connect all electrical harnesses to the new climate control module. Ensure each connector clicks firmly into place and the locking tabs are fully engaged. Slide any secondary locks into their locked positions. Gently tug on each connector to verify secure connection.
9. 9

   Install new climate control module
   Carefully guide the new module into the dashboard opening, ensuring no wires are pinched. Align the mounting screw holes with the dashboard frame. Push the module flush against the frame.

    Reinstall climate control bezel
    Position the climate control bezel over the module and align all clips with their receptacles in the dashboard. Starting at the top, press firmly around the perimeter until all clips snap into place. Ensure the bezel sits flush with no gaps.

Reassembly

1. Reinstall center console side trim panels, ensuring all clips engage properly
2. Reinstall lower dashboard trim panel by aligning clips and pressing firmly until seated
3. Reconnect negative battery terminal
4. Inspect all trim panels for proper fitment and alignment

Verification

• Turn ignition to ON position without starting engine
• Verify climate control module illuminates and display is functional
• Test all climate control buttons and knobs for proper response
• Start engine and verify blower motor responds to speed adjustments
• Test temperature control functionality by adjusting hot and cold settings
• Verify mode selection (defrost, vent, floor) operates correctly
• Test AUTO mode if equipped and verify system auto-adjusts
• Check for any error messages or warning lights on the display
• Verify rear climate controls function properly if vehicle is equipped with dual-zone system
