If there's a control module for this model then it will be located on the back of the fan mounting frame, a silver box about the size of a family pack of matches
however I'm unsure that this model has one?
so I'd next check the condition of the high power fuses in the engine bay fusebox and if there's a relay it should be clicking on when the AC is turned on
