09 G6 GT. when i first start the car in the morning i can hear this clicking sound coming from the engine when idling. sounds like an a/c compressor cycling off and on but the a/c is not on. anyone hear of this or have the same problem??????????? thanks

Check your oil level. Could be the lifters not fully filling with oil and tapping against the push rods. Just a guess though.

not really coming from top of motor. sounds like it's coming towards the wheel. when you first start it up and get out you can hear it down towards the wheel. maybe it is the a/c compressor

the compressor runs quite a bit actually, the only way to truly turn it off is to turn the HVAC system OFF, not something I do often
