how do i find the relay switch on 1999 mondeo glx?

hi i'v just brought a 1999 mondeo glx but the air condition light stays on all the time, i was told to check the relay? so i went and brought a manual, now the thing is the diagram (fuse box) in the manual is diffrent to whats on the car, can anyone please tell me or show me a pic of which relay this is,or could it be something else.
