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).

4. Apply 3M Automotive Adhesion Promoter 06396, or equivalent, to the underside of the reveal molding seals.
Tip
An approximate 600 mm (24 in) length of tape should allow for overlap at the top to be trimmed back leaving a tail of release liner (1) and, at
minimum, should reach the fender cut line at the bottom.
5. Apply a 600 mm (24 in) length of 3M Automotive Acrylic Plus Attachment Tape 06386 (1.14 mm (0.045 in) thick x 6.35 mm (0.25 in)
wide), or equivalent, to both sides of the windshield. Ensure the tape (1) position is centered between the windshield edge (2) and the
tape/grease pencil line (3). Do not remove the release lining from the tape yet.
6. Reinstall the reveal molding to one side by sliding the molding downward and ensuring that the top lip is engaged at the upper edge of the
windshield.

7. Install the fasteners to the reveal molding, starting from the top. Refer to Windshield Side Reveal Molding Replacement in SI.
8. Lifting the top edge of the reveal molding, grab the tail of the release lining and pull downward removing the lining.
9. Press or roll the reveal molding against the windshield ensuring adhesion of the tape to the glass.
10. Repeat steps 6-9 on the opposite side.
11. Remove tape or clean the grease pencil marks from the windshield.
12. If positioned correctly, trimming of the double sided tape should not be necessary, however inspect the reveal moldings for any tape not
covered and trim off any exposed tape.
Important
After taping the windshield reveal moldings, avoid washing the vehicle as well as excessive contact with the windshield reveal moldings for
a minimum of 72 hours.
