A drain trough encircles the sliding window panel and leads to the drain hoses. The drain hoses are located at each corner of the sunroof module assembly. The two front drain hoses route down the windshield pillars and exit out the inner wheelhouse area. The two rear drain hoses route down the rear sail and the quarter panels and exit the rear inner wheelhouse area.

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 at the front and rear inner wheelhouse area.
3. If the water flow is restricted, use a low volume of 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 drain hoses onto the sunroof module assembly drain spouts with new tie wraps.
