Horn Sounds Muffled or Distorted

The horn may sound muffled, distorted or sounds only the high note on some 2018-2020 Enclave and Traverse models. These horn conditions may be caused by a frequency that distorts the horn sound when it reflects off the original horn assembly bracket.

To address the distorted horn sounds, replace the right-side low note horn assembly. (Fig. 16) Refer to Horn Replacement (Right Side) in the appropriate Service Information. The Intake Air Splash Shield must be removed in order to access the horn assembly.
