Parts

• Dashboard speaker × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn off vehicle and remove key fob from cabin
3. Disconnect 12V battery negative terminal and wait 2 minutes before proceeding
4. Identify which dashboard speaker requires replacement (left or right A-pillar area)

Procedure

1. 1

   Remove A-pillar trim panel
   Carefully pull the A-pillar trim panel away from the windshield pillar starting at the top. Use a trim removal tool to release the plastic retaining clips. Work downward and pull the panel away from the pillar completely.
2. 2

   Access dashboard speaker grille
   Locate the speaker grille on the top surface of the dashboard near the A-pillar. The grille is a small rectangular or circular trim piece positioned at the end of the dashboard.
3. 3

   Remove speaker grille
   Use a trim removal tool to carefully pry up the speaker grille from the dashboard. Start at one edge and work around the perimeter. The grille is held by clips and will lift straight up once all clips are released.
4. 4

   Remove speaker mounting screws
   Using a T20 Torx driver, remove the screws securing the speaker to the dashboard mounting bracket (typically 2-3 screws). Keep screws in a safe location for reinstallation.
5. 5

   Disconnect speaker electrical connector
   Lift the speaker partially out of the mounting location to access the electrical connector on the back. Press the locking tab on the connector and pull straight off the speaker terminals. Remove the old speaker completely.
6. 6

   Install new speaker
   Connect the electrical connector to the new speaker, ensuring it clicks into place firmly. Position the new speaker into the dashboard mounting location, aligning the mounting holes with the bracket.
7. 7

   Secure speaker mounting screws
   Install the T20 Torx screws through the speaker and into the mounting bracket. Tighten screws in a cross pattern to ensure even pressure. Do not overtighten as the speaker housing is plastic.
8. 8

   Reinstall speaker grille
   Align the speaker grille over the speaker and press down firmly around the perimeter until all clips snap into place. Ensure the grille is flush with the dashboard surface.
9. 9

   Reinstall A-pillar trim
   Position the A-pillar trim panel against the pillar and align all clip locations. Starting at the bottom, press firmly on each clip location until the panel snaps into place. Work upward to the top of the pillar.
10. 10

    Reconnect battery and test
    Reconnect the 12V battery negative terminal. Turn on the vehicle and test the speaker using the audio system. Test all audio sources and fade/balance controls to verify proper operation.
