Clicking sound, on Engine when ACC is on

Has anyone heard the clicking sound in the Engine compartment when the engine is off and just the ACC is on. Sounds like a relay resetting, but I can't figure out what it is for. Seems to do it about every couple of min. or so.
Any ideas?

Yes, I've heard the same thing. The sound seems to be more then just a relay. Almost like a damper is changing positions or something. You have the frequency correct, seems to happen every few minutes. As far as I can tell its coming from the passenger side engine compartment close to the firewall.
Are you saying it does this when the AC (air conditioning) is on?
My Dakota did something like this too. I haven't had the luxury to turn the AC on in the Nitro yet.
No,it seems to only happen when the accessory switch is on. When you turn the key on, just to listen to the radio or such.
Pepsi, you are correct about the sound area...I wonder if it is just on the R/T's for some reason....??
Nevermind, I just re-read what ya'll were talking about. Disregard my post.
It may actually be the compressor clutch engaging and/or disengaging.
