Parts

• HVAC control panel assembly × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key from vehicle
3. Allow vehicle to sit for at least 10 minutes to allow airbag system capacitors to discharge
4. Disconnect negative battery terminal to prevent electrical shorts during work
5. Set interior temperature controls to mid-range position to facilitate removal

Procedure

1. 1

   Remove center console trim surround
   Starting at the rear of the center console near the gear selector, carefully insert trim removal tools between the trim surround (wood veneer or carbon fiber depending on vehicle specification) and the console body. Work around the perimeter, releasing the spring clips that secure the surround. Release the spring clips that secure the surround, working carefully around the entire perimeter (exact clip count and any hidden fasteners to be confirmed against the 2009 DB9 service manual before prying). Lift the trim surround up and away from the console, being careful not to stress the material. Note: The number of clips securing the trim surround must be verified against OEM documentation for the 2009 DB9; the exact count is not confirmed. Note: The number of retaining clips varies; release each clip progressively around the perimeter per the factory trim layout.
2. 2

   Disconnect gear selector surround (if equipped)
   If the trim surround includes the gear selector bezel, gently lift while pulling rearward to clear the selector lever. The surround should lift over the selector knob. Set the trim piece aside in a safe location where it will not be scratched.
3. 3

   Access HVAC panel fasteners
   With the trim surround removed, locate the Torx fasteners securing the HVAC control panel to the console structure. The number, type, and even existence of threaded fasteners securing the HVAC control panel must be verified against OEM documentation for the 2009 DB9; this era of DB9 may use spring clips or a snap-fit retention rather than corner screws, so do not assume 4 corner T20 fasteners. Remove all fasteners and store them in a magnetic tray. Note: Locate the fasteners securing the HVAC control panel to the console structure (count and Torx size to be verified against the 2009 DB9 service manual). Remove all fasteners and store them in a magnetic tray. Note: Locate the fasteners securing the HVAC control panel to the console structure (count and Torx size per factory documentation for the 2009 DB9). Remove all fasteners and store them in a magnetic tray.
4. 4

   Release panel from mounting position
   Gently pull the HVAC control panel forward from the dashboard opening approximately 2-3 inches. The panel will pivot outward from the top. Support the panel with one hand while preparing to access electrical connections behind it. Do not pull excessively on the panel as wiring harnesses are still connected.
5. 5

   Disconnect primary electrical harness
   Locate the main electrical connector on the rear of the HVAC control panel. This is a multi-pin connector with a locking tab. Press the release tab (typically on top or side of the connector) and pull the connector straight back from the control panel. Use steady, even pressure to avoid bending pins.
6. 6

   Disconnect secondary connectors
   Identify and disconnect any additional electrical connectors attached to the control panel. Identify and disconnect any additional electrical connectors attached to the control panel (exact count to be confirmed against the 2009 DB9 service manual). Note the position and orientation of each connector for reinstallation. Note the position and orientation of each connector for reinstallation. Note: The exact number and function of electrical connectors on the HVAC control panel must be verified against OEM documentation for the 2009 DB9; note and label each connector during removal. Note: Disconnect each additional electrical connector attached to the control panel (number and function per factory documentation for the 2009 DB9). Note the position and orientation of each connector for reinstallation.
7. 7

   Remove HVAC control panel
   With all electrical connections disconnected, fully remove the HVAC control panel from the vehicle. Inspect the mounting brackets and clips on the panel for damage. Set the old panel aside on a clean, protected surface.
8. 8

   Inspect mounting location and connectors
   Examine the dashboard opening and wiring harness connectors for any signs of damage, corrosion, or moisture intrusion. Check connector pins for bending or discoloration. If present, clean connector terminals with electrical contact cleaner and allow to dry completely before proceeding.
9. 9

   Prepare new HVAC control panel
   Remove the replacement HVAC control panel from its packaging. Verify that all mounting brackets and clips are intact. Confirm that the panel matches the original configuration and control layout. Check that all electrical connections are clean and free of protective shipping caps.
10. 10

    Connect electrical harnesses to new panel
    Position the new HVAC control panel near the dashboard opening. Reconnect all electrical connectors in the reverse order of removal, ensuring each connector locks securely with an audible click. Verify that connectors are fully seated and locking tabs are engaged. Gently tug each connector to confirm secure attachment.
11. 11

    Install HVAC control panel into dashboard
    Guide the new control panel into the dashboard opening, ensuring no wiring is pinched behind the panel. Align the mounting holes with the console structure. Push the panel flush with the surrounding surface, checking that it sits evenly without gaps.
12. 12

    Secure panel with fasteners
    Secure the HVAC control panel using the OEM retention method (Torx fasteners and/or spring clips as specified in the 2009 DB9 service manual). Start all fasteners by hand before tightening. Tighten in a cross pattern to ensure even seating. Torque fasteners snugly but do not overtighten, as the panel housing is typically plastic-backed and can crack under excessive force. Note: Install the Torx fasteners at the corners of the HVAC control panel (count per factory documentation).
13. 13

    Reinstall center console trim surround
    Position the trim surround over the center console, aligning it with the gear selector (if applicable). Press firmly around the perimeter to engage all spring clips. Work systematically around the panel, ensuring each clip seats with a positive click. Verify that the trim sits flush and even with no gaps.
14. 14

    Reconnect battery and initialize system
    Reconnect the negative battery terminal. Turn the ignition to the ON position without starting the engine. Observe the HVAC control panel display to confirm it illuminates properly. Check that all buttons respond to input and that the display shows expected information. Note: Disconnecting the battery will reset radio/infotainment presets, may require window and sunroof recalibration, and may require radio security code re-entry or other module/immobilizer re-initialization. Confirm required relearn procedures per the 2009 DB9 service manual. Record settings before beginning work and verify any required relearn procedures per OEM documentation.

Reassembly

1. Reassembly follows removal in reverse order
2. Ensure all electrical connectors are fully seated and locked before securing the panel
3. Do not overtighten Torx fasteners securing the control panel to avoid cracking plastic mounting points
4. Verify trim surround clips engage fully around the entire perimeter before operation

Verification

• Turn ignition to ON position and verify HVAC control panel display illuminates correctly
• Test all HVAC controls including temperature adjustment, fan speed, mode selection, and recirculation
• Verify that air flows correctly through all selected vents at all fan speeds
• Check that automatic climate control responds appropriately to temperature changes
• Confirm heated seat controls (if integrated into panel) function correctly
• Test defrost and demist functions to ensure proper system operation
• Verify no warning lights or error codes related to climate control system
• Perform window recalibration procedure if required after battery disconnection
