If the hoses in and out of heater core are hot, check the air/mix. I can't tell if the pump is starting to. It could be stuck or the actuator is not moving between heat and a/c.

Doesn't always happen, but is unpredictable. The first thing i would recommend checking is to make sure you don't have a big air pocket in the cooling system from when you. Now the temperature gauge reads below normal when driving and blows cold air, but if i leave it idling it gets to normal and will blow somewhat warm. Is your pontiac grand am heater not working?
