there is a second radiator in front of your coolant one, this is the condenser of the coolant flow, running a little hot would advise that you switch it off *to avoid cookin' the whole engine~ a simple turn of a screw to increase the idle when engaged should fix it~ might be sure that the coolant is up to the correct level~

Any trouble codes? Sounds like the idle speed is not increasing when you command the AC on, this could be the IAC is plugged, dirty or the computer is not sending the signals. Now you also stated it had a vibration, so that could be a bad AC compressor, the ignition is breaking down under load so bad spark plugs or low coil output, engine compression low, so a tired engine.
