Remove and replace the climate control module located behind the dashboard center console. This procedure requires partial disassembly of the dashboard trim and disconnection of electrical connectors.

Warnings

Tools required

Parts

• Climate control module × 1 — Use OEM specification
• Trim panel clips (assorted) × 1 — Replacement clips if broken during removal

Preparation

1. Park vehicle on level surface and ensure ignition is off
2. Disconnect negative battery terminal and wait 15 minutes for airbag system discharge
3. Set steering wheel to straight-ahead position
4. Allow interior to reach room temperature if climate control was recently operating
5. Take photos of center console and climate control area for reference

Procedure

1. 1

   Remove lower dashboard trim panels
   Using trim panel tools, carefully pry and remove the lower dashboard knee bolster trim panels on both driver and passenger sides. Start at the bottom edges and work upward to release retaining clips. Set panels aside with clips facing up to prevent damage.
2. 2

   Remove center console front trim
   Remove the center console lower trim panel by releasing clips at the base near the footwell. Disconnect any electrical connectors for auxiliary power outlets or USB ports. Remove T20 Torx screws securing the lower console section (typically 4 screws).

3. 3

   Remove climate control faceplate
   Carefully pry the climate control faceplate starting from the bottom edge using plastic trim tools. The faceplate is secured by multiple clips around the perimeter. Work slowly around all edges to avoid breaking clips. Once loose, pull faceplate forward approximately 2 inches.
4. 4

   Disconnect climate control switches
   With faceplate pulled forward, locate electrical connectors on the rear of the climate control button panel. Press release tabs and disconnect all electrical connectors (typically 2-3 connectors for temperature controls, fan speed, and mode selection). Remove faceplate completely.
   ⚠Support the faceplate while disconnecting connectors to avoid strain on wiring harness
5. 5

   Remove center stack mounting screws
   Locate and remove the T25 Torx mounting screws securing the center stack assembly to the dashboard framework. There are typically 4 screws: two at the top near the air vents and two at the bottom. Store screws in a labeled container.

6. 6

   Pull center stack forward
   Gently pull the entire center stack assembly forward approximately 3-4 inches. Work carefully as wiring harnesses and ductwork are still connected behind. Use a flashlight to inspect rear connections and ensure nothing is binding.
7. 7

   Disconnect HVAC ducting
   Reach behind the center stack and disconnect the HVAC duct connections from the climate control module housing. These are typically friction-fit or secured with plastic clips that can be squeezed to release. Disconnect any hose clamps if present using pliers.

8. 8

   Access climate control module
   Locate the climate control module mounted to the rear of the center stack assembly or within the dashboard framework. It is a rectangular metal or plastic housing approximately 6x4 inches with multiple electrical connectors. Note the orientation and mounting bracket configuration.
9. 9

   Disconnect module electrical connectors
   Disconnect all electrical connectors from the climate control module. Typically there are 2-3 large multi-pin connectors with sliding locks or press-tab releases. Slide locks outward or press release tabs while pulling connectors straight back. Avoid rocking connectors side-to-side.
   ⚠Do not force connectors. Ensure all locking mechanisms are fully released before pulling
10. 10

    Remove module mounting hardware
    Remove the mounting bracket bolts or screws securing the climate control module to its mounting location. Use appropriate Torx or socket tools. Most installations use 2-4 mounting points. Support the module with one hand while removing the final fastener.

    Remove old climate control module
    Carefully extract the climate control module from its mounting location. Maneuver it through the opening behind the center stack, being mindful of any remaining wiring or ductwork. Inspect the mounting area for any damage or debris before installing new module.
12. 12

    Install new climate control module
    Position the new climate control module in the mounting location, ensuring correct orientation. Align mounting holes with brackets. Install mounting bracket bolts finger-tight initially, then torque to specification. Ensure module sits flush against mounting surface.
    ℹ️Verify the new module part number matches the old module before final installation

    Reconnect electrical connectors
    Reconnect all electrical connectors to the climate control module in their original positions (reference photos taken during disassembly). Push connectors firmly until they click into place, then engage all locking mechanisms. Gently tug each connector to verify secure connection.
14. 14

    Reconnect HVAC ducting
    Reconnect all HVAC ductwork to the climate control module housing, ensuring firm seating. Install any duct clips or hose clamps, torquing hose clamps to specification. Verify all duct connections are secure to prevent air leaks.

15. 15

    Reinstall center stack and trim
    Push the center stack assembly back into position in the dashboard. Install and torque mounting bolts to specification. Reconnect climate control switch electrical connectors and snap faceplate into place. Reinstall center console trim panels and lower dashboard panels, ensuring all clips engage properly.

Reassembly

1. Verify all trim panels are fully seated and clips are engaged before reconnecting battery
2. Reconnect battery negative terminal
3. Perform climate control system calibration using Maserati diagnostic software (required for proper operation)
4. Clear any stored fault codes related to climate control module replacement
5. Verify all climate control functions operate correctly before returning vehicle to service

Verification

• Turn ignition to ON position and verify climate control display illuminates without error messages
• Test all fan speed settings from low to high to confirm proper operation
• Verify temperature adjustment works correctly for both driver and passenger sides
• Test mode selection (defrost, floor, vent, bi-level) and verify air flows from correct vents
• Confirm automatic climate control functions operate properly if equipped
• Check for proper cold and hot air temperature output after engine reaches operating temperature
• Verify no air leaks from dashboard vents or ductwork connections
• Ensure all trim panels are secure with no rattles or gaps
