AC problem

When my air conditioner is turned on or off it makes a clicking noise that sounds like it is coming from the passenger side dash. When the air is on it causes the car to idle rough and sometimes the air condition goes in and out and causes the gauges to flat line then go back up. What could be causing this? It only does it when the AC is on.

Check the alternator might not be compensating for the additional electrical load from the magnetic clutch on the compressor-also clean out the idle air control valve and see what happens
