I had that same problem with my truck, an '89 ranger. When I would go, I'd get heat, but when I was stopped, the air would be cold. The problem was fixed when I replaced my water pump, which was seized. I found this out when I had some other work done on my truck. I don't know if that was the root cause, and I really don't know why not having a working water pump didn't ruin my truck, but now I have heat....

In my parent's altima, the same thing was happening. Heat when driving, no heat when idling. I checked the coolant level and it was almost bone dry! I filled it up and no more problems. Might be different in your application, but doesn't hurt to check.

When you rev your car, the engine gets heats up and you get more heat from your vent. When you stop, your engine cools down and the air gets cooler. I don't know why it would be so drastic, but it's a thought. See if you can recreate it when you want, and then take it to the dealer.

I agree with 2000SE. You are probably bringing in outside air when vehicle is moving. Water temperature won't change that much. It's the fan.

I think it might be the thermostat. When you come to a stop the engine is not running hard and the thermostat closes, not allowing any hot water to your heater core. When you speed up the engine gets warmer along with the coolant opening the thermostat. I would first check your coolant level, if that's not it bring it to the dealer. This shouldn't be happening.
