Diagnostic Overview

The Roof Opening Panel Has Excessive Wind Noise

Normal Operation and Fault Conditions

When the roof opening panel glass is completely closed, it should be aligned within specifications. REFER to Roof Opening Panel Alignment . The roof opening panel weatherstrip provides a seal against adverse weather conditions such as rain and wind, preventing them from entering the passenger compartment. A damaged, deformed or incorrectly installed weatherstrip is unable to effectively seal the glass. The roof opening panel air deflector deflects the air flow over the roof opening panel when the panel is in the VENT or OPEN positions, a damaged or incorrectly installed air deflector is unable to effectively deflect the air flow. An incorrectly installed roof opening panel frame may also allow air/wind to leak into the passenger compartment.
