- Is the roof opening panel aligned correctly?
Yes
GO to B3.
No
ALIGN the roof opening panel. REFER to Roof Opening Panel Alignment Adjustments. TEST the system for normal operation.

B3 CHECK THE WEATHERSTRIP CONDITION
NOTE: The weatherstrip has a bonded joint located on the passenger side or rear edge. This is not a defect.
- Make sure the roof opening panel weatherstrip is not cracked, torn or loose.
- Check the roof opening panel weatherstrip.
- Is the roof opening panel weatherstrip in good condition and free from damage?
Yes
GO to B4.
No
INSTALL a new roof opening panel weatherstrip. TEST the system for normal operation.

B4 CHECK THE WATER TROUGH CONDITION
- Check the water trough and guide for damage and/or incorrect attachment and function.
- Is the water trough OK?
Yes
GO to B5.
No
REPAIR the water trough or INSTALL a new component as necessary. TEST the system for normal operation.
-------------------------------------------------
B5 CHECK THE DRAIN HOSES
NOTE: Drain hoses can be viewed with a flashlight by removing the headliner lace around the inside opening and gently pulling down on the headliner. (On some vehicles, hook-and-loop tape style attachments have been installed in place of trim lace.)
- Make sure the drain hoses are all connected and not cracked, slit, pinched or obstructed.
- Are all the drain hoses present and attached correctly?
Yes
GO to B6.
No
REPAIR or INSTALL a new drain hose(s). TEST the system for normal operation.

B6 CHECK THE DRAIN HOSES FOR CORRECT FLOW
NOTE: Drain hoses must flow downhill and cannot be pinched or restricted by headliner or any other trim components. For drain hose routing information, refer to Roof Opening Panel Description and Operation.
- With the panel OPEN, slowly pour water into the water trough area and make sure that the same amount of water exits the vehicle at the bottom of the A- and C-pillars.
- Check the drain hoses for obstructions by blowing compressed air through the drain spouts in the water trough area, then retest with water.
- Are the drain hoses operating correctly?
Yes
INSPECT other areas of the vehicle that may cause water to enter the roof area such as the windshield. If no concern is found, GO to B7.
No
LOWER the headliner and INSPECT the drain hoses for correct routing. REPAIR or INSTALL a new drain hose(s). TEST the system for normal operation.
