There is a clicking sound that emanates from the driver side of my '05 Pontiac G6. It sounds similar to the sound an ignitor on a gas grill makes, only constantly. The noise goes away immediately when I turn the heater & a/c off (to 0), and conversely starts back up when the heater is switched back on. There are very few moments when the noise goes away on its on, but they are very short lived and far between.

Clunking noise front when turning left and does it right also but not as bad 2006 g6 at low speed and goes away as you speed up but always there i have replaced lower control arms both side still there

This sounds like it could be your blower motor.Only the blower motor is on the passengers side of the vehicle under the dash.Try just turning off the blower motor speeds and see if it makes a difference.Also listen on the passengers side under the dash to see if it is the blower motor.If it is you will have to replace the blower motor.
