A drain trough encircles the sliding window panel and leads to the drain hose spouts. 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 window open.
2. Inspect for water drainage through the exit holes.
3. If the water flow is restricted, use a low volume of compressed air in order to clear the restricted drain hose. Do not blow the drain hose away from the housing assembly 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 hose connection. If necessary, secure the hoses onto the housing assembly drain spouts.
