Door Trim/Water Deflector Rattle
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
If the rattle is heard within the door trim, depress the trim with your hand. If the sound changes or the rattle/buzz decreases when pressure is applied, preform the following steps:
- Remove the door trim screw cover behind the door handle on the affected door and apply pressure to the water deflector. If this cures the condition, proceed to the step 3.
- Once the door trim is removed, confirm the perimeter clips are not damaged, bent or missing. Replace damaged door clips. Add flocking tape as needed.
- If the rattle is caused by the water deflector, install two 100 mm (4 in) long layers of 1" x 9/16" adhesive backed foam shim stock, or equivalent, to compress the water deflector as shown in the illustration. Confirm any added foam does not interfere with the window or door lock operation.
- Reinstall all components and verify the condition is corrected using the same audio source that created the condition.
NOTE:
The foam shipping blocks installed on new vehicle door edges can be used to compress the water deflector.
