Look at the dash, if it has controls for ac, it will say so on the defroster/heating/cooling panel.
The wiring may still exist in the harness under the dash, even though it doesn't have the "a/c" dash panel.
Post a closeup pic of the dash control panel, if you will.
A/C can also be wired in to work, but simply, and under driver control
instead of "climate" control.-Bob
