Condition
Some customers may comment on a rattle noise in either front side door or that the upper tweeter speaker has fallen out of position.
Cause
A material incompatibility between the door trim and the door tweeter speaker may cause this condition. Over time, the two posts used to attach the
tweeter to the door trim may fracture.
Correction
New grommets have been released that will be placed over the tweeter speaker posts to isolate the two materials and correct this condition. Grommets
will have to be attached to the current stock of tweeter part numbers. The new tweeters will have the two grommets already attached to the posts.
Replace the tweeter speaker and add grommets as necessary. The door trim panel post holes for any tweeter part number will have to be slightly enlarged
to accommodate the grommets.
Use the following procedure and refer to the Parts Information for the applicable speaker parts/usage.
1.
Remove the front door trim panel. Refer to the Trim Panel Replacement - Side Front Door procedure in the Doors sub-section of SI.
2.
Remove the speaker grille. Refer to the Speaker Grille Replacement - Front Door procedure in the Entertainment sub-section of SI.
3.
Remove the tweeter speaker retaining nuts.
4.
Remove the speaker from the door trim panel.
