Pinpoint Test B : The Roof Opening Panel Leaks: Notes

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions

When the roof opening panel glass is completely closed, it is flush with the roof panel. 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 seal the glass efficiently. The roof opening panel trough assembly and drain hoses provide a route for water to drain away from the opening panel, damaged or obstructed drain hoses or trough assembly will allow water to collect and possibly leak into the passenger compartment.

NOTE: Water may accumulate on both outside front corners of the glass panel after rain or after a car wash. If the glass panel is opened with water in the front corners, this water will fall into the channel for the glass panel track (which is not sealed) and down into the headliner. If the source of a suspected leak cannot be determined, this situation may be the source. This is a normal condition, do not replace any part of the roof opening panel system due to this condition.
