Excessive Wind Noise at Sunroof
Normal Operation and Fault Symptoms
When the sunroof glass is fully closed, it is flush with the roof panel. The sunroof seal provides insulation from adverse weather conditions such as rain and wind, preventing them from entering the passenger compartment. A damaged, deformed or incorrectly installed seal cannot effectively seal the glass. The sunroof air deflector deflects airflow over the roof opening when the panel is in the vent or open positions. A damaged or incorrectly installed air deflector cannot effectively deflect airflow. An incorrectly installed sunroof frame may also allow air/wind to enter the passenger compartment.
Possible Sources
Sunroof panel misaligned
Poorly Fitted Sunroof Seal/Weatherstrip
Incorrect Sunroof Panel and Motor/Module Installation
Incorrect Air Deflector Curvature

Is the wind noise present only in the open position?
Yes
GO to A4
No
GO to A2

Yes
GO to A3
No
INSTALL a new sunroof seal.
A3 CHECK THE SUNROOF PANEL ALIGNMENT
Check the sunroof panel alignment.
Is the alignment correct?
Yes

No
ALIGN the sunroof panel. Refer to: Sunroof Panel Alignment (501-17 Sunroof, General Procedures).
A4 CHECK THE AIR DEFLECTOR
Make sure the air deflector is securely attached.
Is the air deflector in good condition?
Yes
PARTIALLY CLOSE the sunroof until the noise is eliminated. If the noise is eliminated, INFORM the customer that changing the glass position will eliminate the wind noise. If the wind noise is not eliminated, INSTALL a new air deflector. REFER TO: Air Deflector (501-17 Sunroof, Removal and Installation).
No
INSTALL a new air deflector. REFER TO: Air Deflector (501-17 Sunroof, Removal and Installation).
Sunroof Leaks
Normal Operation and Fault Symptoms
When the sunroof glass panel is fully closed, it is flush with the roof panel. The sunroof panel seal provides protection from adverse weather conditions, such as rain and wind, by preventing them from entering the passenger compartment. A damaged, deformed or incorrectly installed seal cannot effectively seal the glass. The sunroof drain trough assembly and drain hoses provide a path for water to drain through the sunroof opening. Damaged or blocked drain hoses or trough assembly will allow water to collect and possibly leak into the passenger compartment.

Sunroof Panel Rattles
Normal Operation and Fault Symptoms
When the sunroof glass panel is fully closed, it is flush with the roof panel. All components must be correctly secured. The sunroof system consists of many components that require specific torque values and correct installation to avoid any NVH concerns. Over time, components may loosen or become damaged. Fasteners may loosen, sound insulation material may wear, and foreign objects may accumulate in the sunroof panel frame. It is possible that one or more of these conditions may cause a rattle concern in the sunroof system.
