The sunroof may not be operating properly and/or the sunroof air deflector may not be functioning properly on some 2017-2023 Acadia (Fig. 1); 2018-2023 Enclave, Traverse; and 2024 Enclave and Traverse Limited models. The clips securing the wind/air deflector may not be secure or may have broken, causing the sunroof to be inoperative.
If this condition is found, the clips should be replaced in order to secure the wind/air deflector.
TIP: Do not replace the sunroof for broken air deflector clips. Replace the clips following the procedure covered in Bulletin #24-NA-003.
Fig. 1
Replace the clips by opening the sunroof to the fully open position. Push the sunroof air deflector (Fig. 2, #2) down and back using a suitable tool to release it from the sunroof housing assembly clips. (Fig. 2, #1) Pull the air deflector up and back to remove it. If the clips are broken, be sure to remove all pieces.
Fig. 2
Place the new sunroof air deflector clips (Fig. 3, #1) into the sunroof housing rails. Gently slide each clip back until the wings of the clip are fully seated into the rail cutouts. Very little downward force is needed. Complete repairs by reinstalling the air deflector and verifying proper sunroof operation.
