Default 1988 HVAC trouble codes

does any one have a list of the 1988 HVAC trouble codes. all i can find is the 1990-1996 codes. In 1988 when you access the HVAC diagnostics through the climate control it gives you 9 different fields when you select each field individually it give you some numbers and values. anyone know how to read these? thanks

8 is System Faults and what's there isn't of much help. If you want to know why it doesn't work, it usually won't tell you.
