Pinpoint Test A: The Roof Opening Panel has Excessive Wind Noise

Normal Operation

When the roof opening panel glass is completely closed, it is flush with the roof panel and correctly sealed. When the roof opening panel glass is in the VENT position, the leading edge of the glass panel should contact the primary seal.

This pinpoint test is intended to diagnose the following:

- Roof opening panel primary seal

- Roof opening panel fixed glass seal

- Roof opening panel front trim panel seal

- Roof opening panel side trim panel seal

- Air deflector assembly

PINPOINT TEST A : THE ROOF OPENING PANEL HAS EXCESSIVE WIND NOISE

A1 VERIFY ROOF OPENING PANEL NOISE

- NOTE: It is normal to have some amount of wind noise when the roof opening panel is in the OPEN position. To determine if the wind noise is excessive, road test the vehicle at approximately 100 km/h (62 mph) with the roof opening panel closed, a single rear door window open and all remaining door windows closed while observing the level of wind noise. If the level of wind noise observed with the roof opening panel open (with all door windows closed) is greater than the wind noise observed with a single rear door window open, the wind noise is excessive.
Road test the vehicle with the roof opening panel in the CLOSED, VENT and OPEN positions.


Is the wind noise present only in the OPEN position?

Yes
GO to A3.

No
GO to A2.

A2 CHECK THE ROOF OPENING PANEL GLASS SEALS

- NOTE: When the roof opening panel sliding glass is in the VENT position, make sure that the leading edge of the glass is in contact with the sliding glass primary seal.
Check the roof opening panel front trim seal, sliding glass primary seal and fixed glass seal to make sure they are fitted properly and not damaged.


Are the roof opening panel front trim seal, sliding glass primary seal and fixed glass seal OK?

Yes
CHECK for other vehicle conditions that could be causing the excessive wind noise. For example, aftermarket windshield wipers, side-view mirrors, HVAC door behind glove compartment, HVAC louvers in instrument panel, or antenna base to trim panel. REPAIR as necessary. TEST the system for normal operation.

No
INSTALL or REPAIR the roof opening panel seal(s) in question as necessary. REFER to Roof Opening Panel - Exploded View or Roof Opening Panel Seal - Primary . TEST the system for normal operation.

A3 CHECK THE SLIDING GLASS PRIMARY SEAL

- Make sure the air deflector is not damaged and is securely attached.

Is the air deflector OK?

Yes
PARTIALLY close the roof opening panel until the noise is eliminated. If the noise is eliminated, INFORM the customer that changing glass location will eliminate the wind noise. If the wind noise is not eliminated, INSTALL a new air deflector. REFER to Roof Opening Panel - Exploded View and Air Deflector . TEST the system for normal operation.

No
INSTALL new air deflector assembly. REFER to Roof Opening Panel - Exploded View and Air Deflector . TEST the system for normal operation.
