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?
|
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?
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

Pinpoint Test D: The Roof Opening Panel is Noisy During Operation
Normal Operation and Fault Conditions
When
the roof opening panel glass closes, it should do so quietly and
smoothly. 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 noise concern in the
roof opening panel system.

frame. REFER to: Roof Opening Panel Frame (501-17 Roof Opening Panel, Removal and Installation). TEST the system for normal operation.
|
|
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.
