A/C System Self-diagnosis Function: Description: Notes
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 all three front air control switches, after 3 seconds all three switches will illuminate. After the three switches illuminate, press the A/C and rear defrost switches simultaneously. 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 ".
