A drain trough encircles the sliding panel and leads to the drain hoses. The drain hoses are located at each corner of the housing. The two front drain hoses route down the windshield pillars. The two rear drain hoses route down the rear sail and the quarter panels.

If you encounter a wet headliner or other water leak, inspect the following areas for the source of the leak:

Verify that the drainage system is not plugged or restricted. Use the following procedure:

1. Using a one pint container, pour water into the drain trough with the sunroof open.
2. Inspect for water drainage through holes.
3. If the water flow is restricted, use compressed air in order to clear the drain system. Do not blow the drain hose away from the housing drain spout.
4. Retest the system.

If water drips from the headliner above the door, lower the headliner as required in order to inspect for a proper drain tube connection. If necessary, reclamp the tubes onto the housing drain spout.
