Default A/C compresor engaging and disengaging on idle

Hi , I have a 2005 RX 330 for about 5 years now , and yesterday I noticed that now the idle is below 500 rpms, and at the same time the a/c compresor keeps going on and off , I can tell by the sound it makes under the hood.

Anyone any idea on whats going on?

Below 500 rpms? thats almost stalling? is the check engine light on? Something doesnt sound right here. As far as the a/c going on/off,thats normal its not rapidly doing this is it?. If you have access to a scan gauge, clear the ecm and see what happens.
