Condition
Some customers may comment on hearing a tapping, clicking or ticking noise at the windshield area. This condition occurs more frequently while
driving at highway speeds and could be exaggerated on vehicles with front bug guard deflectors.
Cause
This condition may be caused by air/wind causing the windshield side reveal moldings to move, generating a noise.
Correction
Remove both windshield reveal moldings, add double-sided tape and re-install the moldings following the steps below:
1. Using tape (1) or a grease pencil, mark the position of the inboard edge (2) of both left and right reveal moldings onto the windshield, following
the contour of the molding.
2. Remove the left and right windshield side reveal moldings. Refer to Windshield Side Reveal Molding Replacement in SI.
3. Being careful not to affect the tape or grease pencil marks, clean and prep the glass at the seal interface with Glass Adhesion Promoter, P/N
12378555 (in Canada, use 88901239).
