Location IV
LOCATION IV: SUNROOF OR HEADLINER AREALocation of Water Leak Source
1. Have an assistant help locate the exact point of water entry.
2. Turn the water pressure to the hose so that a 12" to 18" stream of water is present while the hose is in a vertical position.
3. Make sure the sunroof is completely closed. If necessary, readjust sunroof. (See Workshop Manual Section S.)
4. Run water over the sunroof and note in which area the water enters the vehicle. Refer to the appropriate location's repair procedure. Figure 28.
AREA A: FORWARD HEADLINER AREA
AREA B: REAR PASSENGER COMPARTMENT AREA
AREA C: REAR HEADLINER OR SUNROOF SLIDING PANEL
AREA A: FORWARD HEADLINER AREA
1. Open the sunroof and make sure that the sunroof drain tubes are intact and that no holes are present. If welds are damaged or have holes, repair or replace the sunroof frame.
2. If welds and drain tubes are OK, remove the front header and side trim pieces. Remove the headliner retainer clips (2 metal and 1 plastic per side), sunroof welt, and sun visor.
3. Carefully lower the headliner. Using a flashlight, check that the drain hose tubes are attached to the sunroof frame. Figure 29.
4. Direct a small stream of water into sunroof drain holes to make sure the drain tubes do not leak. If leaking is present, check for damaged hoses.
5. If the hoses are damaged, install a replacement piece of hose which provides a tight fit to the existing hose. The outside diameter of the replacement hose should he 9.5 mm (3/8 in).
AREA B: REAR PASSENGER COMPARTMENT AREA
1. Remove rear header trim, rear shoulder mounts, and inside "C" pillar trim panel(s). Figure 30.
Hint:
Leave lower attaching screws in place and tilt "C" pillar trim back.
Caution:
Do not use too much force when pulling on the "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 the outer rear side molding.
3. Open the sunroof and, using a squeeze bottle filled with water, pour water down the rear drain holes. Check for signs of leakage at the sunroof drain tube-to-drain hose.
4. If necessary, position the hose so that there are no loops, kinks or pinched areas. Check for kinks at the drain hose clip. Repeat the water test. Make sure that the sunroof drains properly and does not leak. Figure 31.
5. If necessary, install a new hose.
6. If hose routing is OK and hose is intact, check for leaks at the rear window.
AREA C: REAR HEADLINER OR SUNROOF SLIDING PANEL
1. Remove the rear header trim, rear shoulder seatbelt mounts, and inside "C" pillar trim panel(s). Figure 30.
Hint:
Leave lower attaching screws in place and tilt "C" pillar trim back.
Caution:
Do not use too much force when pulling on the "C" pillar trim. Permanent damage (white stress marks) may result.
2. Remove headliner retaining clips (1 plastic and 3 metal per side.)
Caution:
Do not remove the 2 center plastic retaining clips.
3. Make sure that the drain hose routing is correct. Check for damage along the drain hoses by pulling down the headliner.
4. Check that the drain hoses are attached to the sunroof drain tubes. Replace hose(s) as necessary. Check for kinks at the drain hose clip. Figure 31.
Caution:
Use care when pulling the headliner down. If it is pulled too far, the headliner will be permanently detached from the hidden bracket.
5. Check if welds around the rear sunroof drain tubes are intact and drain properly. With the sunroof closed, direct water over the sunroof and check for leaks at the drain tubes. If the welds are damaged or have holes, repair or replace the sunroof frame.
