Probably Low Freon level. Unfortunately, unless it's been retrofitted to R-134a, your '90 Riviera will use R-12 refrigerant and you will have to take it to a Certified AC Mechanic to get it charged up to capacity.
When you try to use the AC with the low refrigerant level, the low pressure switch is tripping...setting a Code (I think 447). By removing the battery cable, you are re-setting the code. NOTE: On a 1990 Riviera, you can just go into the 'Service Mode' on your digital dash and 'Clear' the codes that way...without having to remove the battery cable! Look at Section 6.2 in a Haynes Service Manual for instructions on how to enter Service Mode and get the diagnostic codes.
