1.
The "OFF" status indicator is illuminated whenever the BCM commands the air inlet valve to the recirculation position.
2.
The "AUTO" status indicator is illuminated whenever the up-down air control switch on the CCP is in the "Normal" position.
3.
The "FRONT DEFOG" status indicator is illuminated whenever the BCM is requesting the PCM/ECM to engage the compressor clutch. The light
does not indicate whether the clutch is enabled or disabled by the PCM/ECM, and actual operation depends on the PCM/ECM and the integrity of
the compressor clutch system.
4.
The "REAR DEFOG" status indicator is illuminated whenever the BCM senses that the low refrigerant pressure switch is open. The light should
remain off if the refrigerant system is fully charged and being properly controlled. However, when the ambient temperature drops below
approximately -5°F (-21°C), the light will come on due to the pressure temperature relationship of refrigerant R-12.
5.
The "LO FAN" status indicator is illuminated whenever the BCM is commanding the A/C-DEF mode door to divert air flow to the A/C outlets, as
in the A/C or normal purge modes.
6.
The "HI FAN" status indicator is illuminated whenever the BCM is commanding the HVAC programmer to not supply vacuum to the park brake
release motor (park brake remains applied). This light will be off whenever the BCM commands the park brake to be released.
