SUNROOF UNIT ASSEMBLY

Inspection

WIND DEFLECTOR

1. Open glass lid assembly fully.
2. Visually check for proper installation, damaged/deteriorated components, or foreign objects within mechanism. Correct as required for smooth operation.

3. Check for grease at the wind deflector arm (1) and pivot areas. If necessary, apply a sufficient amount of grease for non-binding operation. Arrow Indicates Vehicle front

4. Check that the wind deflector (1) moves freely within the sunroof unit assembly while manually pressing down and releasing. If a malfunction is detected, remove the sunroof unit assembly and visually inspect; refer to "Inspection". If damage is found, replace either wind deflector (1) or sunroof unit assembly as required. Arrow Indicates Vehicle front

LINK AND WIRE ASSEMBLY

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

1. Check link to determine if coating film has peeled off excessively enough that substrate is visible. Check also to determine if link is the source of noise. Replace as necessary.
2. Visually check to determine if a sufficient amount of grease has been applied to wire or rail groove. If not, add grease as required.
3. Check wire for any damage or deterioration. If any damage is found, replace sunroof unit assembly.

WEATHERSTRIP

1. Visually check weatherstrip for damage, deterioration, or deformation.

• Open glass lid assembly partially to inspect front edge of weatherstrip.
• Tilt up glass lid assembly fully to inspect sides and rear edge of weatherstrip. If any area of the weatherstrip is found to be damaged, replace the glass lid assembly. Refer to See: Service and Repair\Removal And Installation.

2. Check for leakage around glass lid assembly.

• Close glass lid assembly.
• Pour water around surface to determine area of concern.
• For gaps or misalignment, adjust glass lid assembly to specifications. Refer to "Inspection".
• For damaged sealing surfaces, either replace glass lid assembly See: Service and Repair\Removal And Installation, or repair the panel .

DRAIN HOSES

Sedan Models

1. Remove the headlining. For Sedan Refer to See: Interior Moulding / Trim\Headliner\Service and Repair\Removal And Installation\Sedan. For Coupe Refer to See: Interior Moulding / Trim\Headliner\Service and Repair\Removal And Installation\Coupe
2. Visually check drain hoses for:

• Proper connection at sunroof unit assembly drain hose connector(s).
• Damage, pinch, cracks, deterioration.
• Proper fastening and routing on body panels.

3. Pour water through drain hoses to determine watertight performance. If damaged or leaking portions in any drain hose is found, replace entire drain hose as necessary.

ADJUSTMENT

CAUTION:

Height Adjustment

1. Tilt glass lid assembly up and down several times using sunroof switch to check that it operates smoothly.
2. Check height difference between roof surface and glass lid assembly surface, then compare to specifications.
3. If necessary, adjust height difference by using the following procedure.

• Loosen glass lid assembly bolts.
• Manually raise/lower glass lid assembly until height difference is within specification.

NOTE:
If necessary, shims may be added between sunroof unit assembly and roof to increase adjustment range. Refer to "Inspection".
