'90 V8 Q codes in Climate Control

Fri Sep 1 00:02:33 EDT 2000

Does anyone know what the codes are (1-21) that come up on the climate
control when you press OUTSIDE TEMP and off at the same time. I know that
they are diagnostics, i.e. #12 (or 11) is current battery voltage, and the
previous one is # of Starts in the past 50, where the voltage has dropped
below a certain level.

If you know them or know where I can find them, please let me know.
