SERVICE INFORMATION FOR ELECTRICAL INCIDENT
Revision: November 20092006 QX56
UNDER SEATING AREAS
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or
pinching.
Heat Sensitive
The customer's concern may occur during hot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60°C (140 °F). If incident occurs
while heating the unit, either replace or properly insulate the compo-
nent.
Freezing
The customer may indicate the incident goes away after the car
warms up (winter time). The cause could be related to water freezing
somewhere in the wiring/electrical system.
There are two methods to check for this. The first is to arrange for
the owner to leave his car overnight. Make sure it will get cold
enough to demonstrate his complaint. Leave the car parked outside
overnight. In the morning, do a quick and thorough diagnosis of
those electrical components which could be affected.
The second method is to put the suspect component into a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the reoccurrence of the incident. If it occurs, repair or
replace the component.
Water Intrusion
The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the incident could be caused by water intru-
sion on an electrical part. This can be simulated by soaking the car
or running it through a car wash.
Do not spray water directly on any electrical components.
Electrical Load
The incident may be electrical load sensitive. Perform diagnosis with
all accessories (including A/C, rear window defogger, radio, fog
lamps) turned on.

Removal and InstallationEIS004TQ
REMOVAL
1. Remove inside mirror. Refer to GW-73, "Removal and Installation" .
2. Partially remove the headlining (front edge). Refer to EI-38, "
HEADLINING" .
3. Remove cowl top cover. Refer to EI-18, "
Removal and Installation" .
4. Apply a protective tape around the windshield glass to protect the painted surface from damage.

Remove glass using piano wire or power cutting tool and an inflatable pump bag.

If the windshield glass is to be reused, mark the body and the glass with mating marks.
WARNING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help prevent
glass splinters from entering your eyes or cutting your hands.
CAUTION:

When the windshield glass is to be reused, do not use a cutting knife or power cutting tool.

Be careful not to scratch the glass when removing.

Do not set or stand glass on its edge. Small chips may develop into cracks.
INSTALLATION

Use a genuine NISSAN Urethane Adhesive Kit (if available) or equivalent and follow the instructions fur-
nished with it.

While the urethane adhesive is curing, open a door window. This will prevent the glass from being forced
out by passenger compartment air pressure when a door is closed.

The molding must be installed securely so that it is in position and leaves no gap.
