Xterra XE 4WD V6-3.3L SC (VG33ER) (2002)
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.
Freezing
FREEZING
The customer may indicate the incident goes away after the car warms up (wintertime). 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 the car overnight. Make sure it will get cold enough to demonstrate
the 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.
Heat Sensitive
HEAT SENSITIVE
The owner's problem 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 component.
