Climate Control Blowing Cold when at Idle
Been having trouble lately with my climate control.
When I'm at idle, no matter what heat setting I have my car at, it blows cold- warm at first, but then over about 10 seconds, it goes from the normal setting to absolute cold.
A/C doesn't seem to have been affected. this only seems to happen when the car is at idle- when I put it into neutral and give it a little gas (say up to 1,500rpm), then the heat comes back onto the setting I had it at.
The problem seems to go away over time (i.e. if I take a big trip over an hour or so).
Any thoughts before I take it to a mech and spend $200 to get it diagnosed?
Thanks!

Change the coolant and thermostat 
That was the easiest 'fix' in the world.

Make sure you bleed the system for any air pockets that might get trapped.
I had the same problem not too long ago.
