Important: The drain hoses are pushed on as an interference fit and are not clamped
or cemented. Do NOT disconnect the hose from the drain channel spouts while
cleaning.
A drain trough encircles the sliding panel which leads to the drain
spouts and into the hoses. The drain hoses are located at each corner of the
housing. The two front drain hoses route down the windshield pillars
and exit out the hinge pillars between the door hinges. The two
rear drain hoses route down the rear sail and the quarter panels and exit
the inner wheelhouse panels.
If you encounter a wet headliner or other water leak, inspect the following
areas for the source of the leak:
Verify the drainage system is not plugged or restricted. Use the following
procedure:
- With the sunroof open use a one pint container, pour water into
the drain trough.
- Open the front doors.
- Inspect for water drainage exiting through the grommets at the
hinge pillar.
- Look at the rear of the inner wheelhouse panels for water exiting
the rear drain hoses.
- If the water flow is restricted, use a low volume of compressed
air in order to clear the drainage system.
- Retest the system.
- If water drips from the headliner above the door, lower the headliner
