I recently noticed that my vent/defrost will only blow warm air when I'm moving at a decent speed, about 20+ mph. If I'm sitting still at a light or in traffic, it will only blow cold air. Any ideas on what can be causing this?

We may need to start a sticky thread on this. I say low coolant too.
Does anyone one know where the coolant bleed valve is for the G6? I'll look as soon as my wife gets home.
