Rapidly turning on and off and not making the air cold is a sign of low coolant and you'll need service for the leak and recharge.
I've tried for a while to get it to engage on command; you know, try to figure out why its engaging. From what I see, its happening at idle only, and about every 30 seconds or so, for about 1 second engaged at a time.
I haven't really tried running the AC to see how that works, it should have been one of my first steps.
