My AC condenser cycles constantly, even when the AC is not selected.

What is your question?

A few years ago I saw a mechanic because it was not blowing cool air. He put in a little coolant and replaced the AC Clutch relay. Worked good. For a while I've heard something cycling, it was my AC condenser. Not much cool air again. I replaced the relay again and the cycling stopped, until I selected AC. It now continues to cycle constantly again, AC on or off...Suggestions?
