Sunroof Buffeting Noise (Install New Deflector)

Some customers may comment on a buffeting type noise when the sunroof is fully opened at speeds of 56 km/h (35 mph) and above.

A new air deflector has been designed to change the air flow across the roof and will help to eliminate this noise. Follow the procedure below to install the new deflector.

1. Open the sunroof.
2. Remove the original air deflector following the procedures in SI.




Important:  The gauge block has two arrows that point to the front of vehicle when positioned with the proper RH or LH designation.




3. The gauge block should be placed initially forward of the wind deflector pivot bracket. Slide the gauge block rearward until the locating arm contacts the pivot bracket. With the gauge block touching the pivot bracket, apply pressure to the gauge block in an outboard direction, with the locating arm pointing to the outside of the vehicle. Refer to the illustration above.
4. Using a 2 mm (5/64 in) drill, it is CRITICAL to drill a hole straight up and down through the appropriate hole in the gauge block, penetrating the track by a maximum of 5.0 mm (¼ in).
5. Clean the channel of drill shavings.
6. Install the new deflector.
7. Upon installation of the air deflector, the sunroof should be cycled closed. There will be a slightly noticeable difference in the speed of the glass movement. The glass should then be cycled fully open then fully closed 10 times. This will break in the spring and mechanism, returning the sunroof to normal smooth operation. In some cases, the sunroof may stop at the air deflector attaching point. Cycling the sunroof will overcome this and return to normal operation.
