MOONROOF PANEL WIND NOISE





On some TMC Camry vehicles, wind noise from the moon roof panel may be present. In order to provide a tighter fit and more complete seal, the sliding roof glass panel has been improved. The improved sliding roof glass incorporates shim stock (Tilt Roof Glass Pad, 800 mm x 4 mm, t = 0.9 mm) in front of the flange on the sliding roof inner panel (see illustration).

PRODUCTION EFFECTIVE:

Production Effective: JT2*G12K*T-0341544 (5S-FE)
JT2*F12K*T-0132461(1MZ-FE)

REPAIR PROCEDURE:

Use the steps below to correct for wind noise:

STEP 1 - VERIFY CONDITION:

Determine the conditions at which the wind noise occurs (speed, wind direction, etc.). Test drive vehicle to identify the type of noise and confirm the location of the noise (front, rear, corners, etc.).

Moonroof closure (slide or tilt operation) may be a critical factor. If the problem occurs after one operation and not the other, make certain that the drive gear and drive rails are properly aligned (refer to repair manual for adjustment procedures).

STEP 2 - VISUAL INSPECTION:

From a visual inspection, determine what type of field-fix repair is required:

^ Over/under flushness of the moon roof panel to the roof panel. (Step 3 - Method A)

^ Gaps between the weather-strip and the roof panel (Step 3 - Method B)

NOTE:
The following adjustments must be correct before proceeding with moon roof panel field-fix repairs.

^ Positioning of moon roof panel to the cutout in the roof panel (front to rear, left to right and centering)

^ "Match Mark" alignment (correct phasing of motor/drive cables, refer to repair manual for specific adjustment procedures).

STEP 3 - FIELD-FIX REPAIRS:

METHOD A - FLUSHNESS (SHIMMING) ADJUSTMENT:

1. Measure and record the "before" and "after" readings on the repair order for flush ness levels between the sliding roof weatherstrip and the roof panel to verify that they are within the following ranges:

^ Front edge + 1.0 +/- 1 mm

^ Rear edge 0 +/- 1 mm

2. Adjust flush ness by adding or removing shims.





Torque settings for the stud nuts securing the moonroof have been revised as shown.

METHOD B - WEATHERSTRIP SEALING INSTRUCTIONS:

1. Remove moon roof panel as specified in the repair manual.





2. Insert section of shim stock (Tilt Roof Glass Pad, P/N 63239-33011) to front edge of the metal flange on the sliding roof inner panel (see figure below).

HINT:
It may be easier to add the shim stock working from the center outward.
