Again Bruce is correct however that model has an A/C amplifier that is a small black box about the size of a mans wallet. It should be visable if you remove the right side under dash cover. If it is not RH drive you can slip the rubber gromest on the glove box and see it there. Disconnect it and see if the A/C shuts off.
I fixed a Honda with a simiiar problem and that was a bad fan relay with fed the voltage back to the A/C clutch, keeping it on.
Good Luck Losone
