A/C System Self-diagnosis Function: Description
WARNING: This page is about a different car, the 2004 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
The self-diagnostic system diagnoses sensors, door motors, blower motor, etc. Refer to applicable sections (items) for details. Shifting from usual control to the self-diagnostic system is accomplished by turning the ignition switch ON and pressing the down fan arrow switch while turning the passenger temperature dial in either direction (hold momentarily). Within 3 seconds of doing this, press the AUTO switch. The fan bars will flash and the ambient temperature display will indicate 0° during the self-diagnosis. Fault codes (if any are present) will be displayed in the ambient temperature display area. Refer to "SELF-DIAGNOSIS CODE CHART ".
