You have the automatic temperature control. If you select vent all you get is outside air and the AC is turned off. I had the same problem when I bought my 96. I pressed the vent button and expected AC but all I got was warm air.
My 96 manual says:

Manual Cooling
The air conditioner works best if you keep your windows closed. On very hot days, open the windows just long enough for the hot air to escape. Press the arrows on the TEMP ,SET switch to set a comfortable temperature. Press RECRCULATE. After cool-down, adjust the airflow to another setting. The compressor works in all settings except VENT and HEATER, and at all temperatures above freezing. Press the arrows on the fan’ speed switch if you don’t like the automatic setting. In AUTO FAN on hot days,the fan speed will be low at first to help get rid of the hot inside air. When the air conditioner is on, you may notice slight changes in your vehicle’s engine speed and power. This normal because the system is designed to cycle the compressor on and off to keep the desired temperature and help fuel economy.
