Pinpoint Tests

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

Normal Operation and Fault Conditions

When the roof opening panel glass is completely closed, it is flush with the roof panel. The roof opening panel weatherstrip provides a seal against adverse weather conditions such as rain and wind, preventing them from entering the passenger compartment. A damaged, deformed or incorrectly installed weatherstrip is unable to effectively seal the glass. The roof opening panel air deflector deflects the air flow over the roof opening panel when the panel is in the vent or open positions. A damaged or incorrectly installed air deflector is unable to effectively deflect the air flow. An incorrectly installed roof opening panel frame may also allow air/wind to leak into the passenger compartment.

Possible Sources

Incorrect roof opening panel alignment
Poorly fitting roof opening panel seal/weatherstrip
Incorrect installation of the roof opening panel and module
Incorrect curvature of the air deflector

Visual Inspection

Roof opening panel air deflector assembly
Roof opening panel seal

If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the pinpoint test.

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

A1 VERIFY ROOF OPENING PANEL NOISE

Road test the vehicle with the roof opening panel in the closed and open positions.

Is the wind noise present only in the open position?

Yes

GO to A4

GO to A2

A2 CHECK THE ROOF OPENING PANEL WEATHERSTRIP

NOTE: Make sure the weatherstrip is secured to the glass, not cut, cracked, pinched, loose or obstructed in CLOSED, VENT and OPEN positions.
Check the roof opening panel weatherstrip.

Is the roof opening panel weatherstrip OK?

Yes

GO to A3

No	INSTALL a new roof opening panel weatherstrip. TEST the system for normal operation.

A3 CHECK THE ROOF OPENING PANEL ALIGNMENT

Check the roof opening panel alignment.

Is the alignment OK?

Yes

CHECK for correct installation of the roof opening panel and module.
REFER to: Roof Opening Panel Motor (501-17 Roof Opening Panel, Removal and Installation).
and REFER to: Roof Opening Panel Frame (501-17 Roof Opening Panel, Removal and Installation).
TEST the system for normal operation.

No	ALIGN the roof opening panel. REFER to: Roof Opening Panel Alignment (501-17 Roof Opening Panel, General Procedures). TEST the system for normal operation.

A4 CHECK THE AIR DEFLECTOR

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

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, ALIGN the roof opening panel.
REFER to: Roof Opening Panel Alignment (501-17 Roof Opening Panel, General Procedures).
TEST the system for normal operation.

No	INSTALL new air deflector. REFER to: Air Deflector (501-17 Roof Opening Panel, Removal and Installation). TEST the system for normal operation.

Pinpoint Test B: The Roof Opening Panel Leaks

Normal Operation and Fault Conditions

When the roof opening panel glass is completely closed, it is flush with the roof panel. The roof opening panel weatherstrip provides a seal against adverse weather conditions such as rain and wind, preventing them from entering the passenger compartment. A damaged, deformed or incorrectly installed weatherstrip is unable to seal the glass efficiently. The roof opening panel trough assembly and drain hoses provide a route for water to drain away from the opening panel, damaged or obstructed drain hoses or trough assembly will allow water to collect and possibly leak into the passenger compartment.

NOTE: Water may accumulate on both outside front corners of the glass panel after rain or after a car wash. If the glass panel is opened with water in the front corners, this water will fall into the channel for the glass panel track (which is not sealed) and down into the headliner. If the source of a suspected leak cannot be determined, this situation may be the source. This is a normal condition, do not replace any part of the roof opening panel system due to this condition.

Pinpoint Test C: The Roof Opening Panel Rattles

Normal Operation and Fault Conditions

When the roof opening panel glass is completely closed, it is flush with the roof panel. The roof opening panel system is made up of many components that require specific torque specifications and correct installation in order to avoid any NVH concerns. Over time, components may become loose or damaged, fasteners may become loose, sound insulating material may wear out and foreign material may collect in the roof opening panel frame. It is possible that one or more of these conditions may lead to a rattle concern in the roof opening panel system.

Pinpoint Test E: The Roof Opening Panel Does Not Open or Close

Refer to Wiring Diagrams Cell 101 for schematic and connector information.

Normal Operation and Fault Conditions

The roof opening panel uses an integrated motor/module to operate the roof opening panel. A new roof opening panel module is installed as an assembly.

The roof opening panel module receives voltage from the CJB fuse 35 (20A) at all times, and from fuse 8 (7.5A) when the ignition is in ON or RUN. The roof opening panel switch (part of the overhead console switch assembly) receives voltage from the roof opening panel module and then supplies voltage signals back to the roof opening panel module to operate the roof opening panel, depending on switch position.
