Water Drainage System Check and Water Leak Corrections

Water Drainage System Check and Water Leak Corrections

1. The roof opening panel module assembly has 2 drain channels which are located under the side trim panels to direct water externally to the front and rear corners of the roof. There are no drain hoses in this system.

If a drainage system blockage or obstruction is suspected, pour a small amount of water into the suspected drain channel while observing the front and rear channel openings for any water flow restriction. Attempt to clear any blockage or obstruction using compressed air at the front or rear opening of the drain channel.

If the blockage or obstruction cannot be cleared, the roof opening panel front trim and/or side trim must be removed to gain full access to the drain channel. For additional information, refer to Roof Opening Panel Trim - Front Roof Opening Panel Trim - Front and Roof Opening Panel Trim - Side Roof Opening Panel Trim - Side.
