IV. Sunroof or Headliner Area

Locating Source of Water Leak

1. Have an assistant help locate the exact point of water entry.

2. Turn water pressure on hose so that a 12" - 18" stream of water is present while hose is vertical.

3. Make sure sunroof is completely closed. If necessary, readjust sunroof. See appropriate Workshop Manual for adjustment procedure.






4. Run water over sunroof. Note which area water enters the vehicle. Refer to the appropriate Inspection and Repair: A, B or C. Figure 25.
A - Forward Headliner Area
B - Rear Passenger Compartment Area
C - Rear Headliner or Sunroof Sliding Panel


Inspection & Repair

Area A: Inspect forward headliner area.



1. Open sunroof and make sure sunroof drain tubes are intact and no holes are present. If welds are damaged or have holes, repair or replace sunroof frame.

2. If welds and drain tubes are okay, remove front header and side trim pieces. Remove headliner retaining clips (two [2] metal and one [1] plastic per side), sunroof welt and sun visor.






3. Carefully lower headliner. Using a flashlight, check that drain hose tubes are attached to sunroof frame. Figure 26.

4. Direct a small stream of water into sunroof drain holes to make sure drain tubes do not leak. If leaking is present, check for damaged hoses.

5. If hose(s) are cut through, install a replacement piece of hose which provides a tight fit to existing hose. Outside diameter of replacement hose should be 9.5 mm (3/8 in).



Area B: Inspect the rear passenger compartment area.






1. Remove rear header trim. Remove rear shoulder seatbelt mounts and inside "C" pillar trim panel(s). Figure 27.

HINT:
Leave lower attaching screws in place and tilt "C" pillar trim back.

CAUTION:
Do not use too much force when pulling on "C" pillar trim. Permanent damage (white stress marks) may result.

2. Make sure sunroof drain hose grommets are seated. Check that the sunroof drain hose is not kinked and extends through outer rear side molding.



3. Open sunroof. Using a squeeze bottle filled with water, pour water down rear drain holes. Check for signs of leak at sunroof drain tube-to-drain hose.





4. If necessary, position hose so there are no loops, kinks or pinched areas. Check for kinks at drain hose clip. Repeat water test. Make sure sunroof drains properly with no leaks. Figure 28.


5. If necessary, install a new hose.

6. If hose routing is okay and hose is intact, check for leaks at rear windshield.

Area C: Inspect rear headliner or sunroof sliding panel.





1. Remove rear header trim. Remove rear-shoulder seatbelt mounts and inside "C" pillar trim panel(s). Figure 27.

HINT:
Leave lower attaching screws in place and tilt "C" pillar trim back.

CAUTION:
Do not use too much force when pulling on "C" pillar trim. Permanent damage (white stress marks) may result.



2. Remove headliner retaining clips (one [1] plastic and three [3] metal per side).

CAUTION:
Do not remove the two (2) center plastic retaining clips.



3. Make sure drain hose routing is correct. Check for damage along drain hoses by pulling down headliner.





4. Check that drain hoses are attached to the sunroof drain tubes. Replace hose(s) as necessary. Check for kinks at drain hose clip. Figure 28.

CAUTION:
Use care when pulling headliner down. If pulled down too far, headliner will be permanently detached from hidden bracket.

5. Check if welds around rear sunroof drain tubes are intact and drain properly. With sunroof closed, direct water over sunroof and check for leaks at drain tubes. If welds are damaged or have holes, repair or replace sunroof frame.
