Initial Inspection and Diagnostic Overview

Trouble Diagnoses

Diagnostic Table:

WIND DEFLECTOR
1. Open lid.
2. Check visually for proper installation.




3. Check to ensure a proper amount of petroleum jelly has been applied to wind deflector connection points; apply if necessary.




4. Check that wind deflector is properly retracted by hand. If it is not, remove and visually check condition. (Refer to removal procedures.) If wind deflector is damaged, replace with new one. If wind deflector is not damaged, re-install properly.




ADJUSTMENT
If any gap or height difference between glass lid and roof is found, check glass lid fit and adjust as follows:

Gap Adjustment
1. Open shade assembly.
2. Tilt glass lid up then remove side trim.
3. Loosen glass lid securing nuts (3 each on left and right sides), then tilt glass lid down.
4. Adjust glass lid from outside of vehicle so it resembles "A-A" as shown in the figure.
5. Tilt glass lid up and down until it is adjusted to "B-B" as shown in the figure.
6. After adjusting glass lid, tilt glass lid up and tighten nuts.
7. Tilt glass lid up and down several times to check that it moves smoothly.

Height Difference Adjustment
1. Tilt glass lid up and down.
2. Check height difference between roof panel and glass lid to see if it is as "A-A" as shown in the figure.
3. If necessary, adjust it by using one of following procedures.
- Adjust by adding or removing adjustment shim(s) between glass lid and link assembly.
- If glass lid protrudes above roof panel, add shim(s) or plain washer(s) at sunroof mounting bracket or stud bolt locations to adjust sunroof installation as required.




DRAIN HOSES




1. Remove headlining to access drain hose connections. (Refer to "ROOF TRIM", for details.)
2. Check visually for proper connections, damage or deterioration. A (The figure shows only the front side.)




3. If leakage occurs around luggage room, remove luggage room side trim and check connecting area. Check for proper connection, damage or tear. B
4. Remove drain hoses and check visually for any damage, cracks, or deterioration.
5. Pour water into drain hoses and find damaged portion.
- If any damaged portion is found at each step, replace the damaged part.

WEATHERSTRIP
- In the case of leakage around glass lid, close glass lid and pour water over glass lid to find damaged or gap portion.
1. Remove glass lid assembly. (Refer to removal procedures for details.)
2. Visually check weatherstrip for proper installation. If a gap exists between glass lid and weatherstrip, check for sufficient amount of butyl seal. If required, remove weatherstrip and apply butyl seal.
Refer to "EXTERIOR" for details.
3. Check weatherstrip visually for any damage, deterioration, or flattening.
- If any damage is found, replace weatherstrip.

CAUTION: Do not remove weatherstrip except when replacing, or filling up butyl seal.

LINK AND WIRE ASSEMBLY

NOTE: Before replacing a suspect part, carefully ensure it is the source of noise being experienced.

1. Check link to determine if coating film has peeled off to such an extent that substrate is visible. Check also to determine if link is the source of noise. If it is, replace it.
2. Visually check to determine if a sufficient amount of petroleum jelly has been applied to wire or rail groove. If not, add petroleum jelly as required.
3. Check wire for any damage or deterioration. If any damage is found, remove rear guide (refer to removal procedures for details), then replace wire.
