PROCEDURE
1. Verify the specific noise complaint with the customer. Note the audio setting at which the noise occurs (volume, bass, treble, fader, and balance control positions).
2. To determine the location of the noise, press a suspect area with your hand. The location is identified if the noise stops when you press it, and starts again when you release.
a. If the noise seems to come from the window control switch, door release handle, or grab handle areas, go to Step 3.
b. If the noise is speaker-related, refer to TSB-04-54-002REV for audio speaker troubleshooting procedures.
3. After determining the location of the noise, use the appropriate repair procedure below:
a. Vibration at window switch may be caused by:
- Window switch bezel lock tabs contacting the door panel.
The door panel fabric may be improperly positioned under the panel trim. This condition allows the bezel lock tabs to contact the trim panel and causes the vibration noise.
Remove the window switch switch and bezel. Fold the door panel fabric neatly down around the trim opening.
Reinstall the bezel and window switch securely.
- Window switch bezel locator pin.
Remove the window switch and bezel from the door panel. Remove the switch from the bezel by removing two screws. Install a small piece of felt around the locator pin as shown
Then reinstall the window switch to the bezel, and reinstall the bezel to the door panel.
b. Vibration at the grab handle may be caused by the plastic tab under the grab handle.
Remove the grab handle. Install a small piece of felt under the plastic tab in the opening as shown. Reinstall the grab handle.
c. Door release handle trim vibrating against the door panel.
Remove the door release handle and trim from the door. Install a narrow piece of felt around all of the handle trim edges.
Reinstall the handle and trim securely.
4. Confirm the noise is eliminated by test driving the vehicle with the audio operating at various volume levels and bass/treble settings.
