Pinpoint Test A: Sunroof Panel Has Excessive Wind Noise
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.

Pinpoint Test B: Sunroof Panel 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.
