Title: MOONROOF PANEL WIND NOISE





On some ES 300 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 the front of the flange on the sliding roof inner panel (see illustration).

PRODUCTION EFFECTIVE:

Starting VIN: JT8GK13T-S0108922

REPAIR PROCEDURE:

Use the steps below to correct for wind noise:

STEP 1 VERIFY CONDITION:

Determine the conditions at which the problem 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.).

Moon roof 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 moonroof panel to the roof panel (step 3A)

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

NOTE:
The following base 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 flushness levels between the sliding roof weatherstrip and the roof panel to verify that they are within the following ranges:

^ Front end +1.0 +/-1 mm

^ Rear end 0 +/-1 mm

2. Adjust flush ness by addin9 or removing shims (refer to TSB BO95-007 for torque values of nuts).

METHOD B - WEATHERSTRIP SEALING INSTRUCTIONS:

1. Remove moonroof 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.
