Why does my heat only work when I accelerate?

Why does my heat stop working when I stop?
Often, the issue is that the heating system is simply dirty. If your furnace has a dirty blower, the blower could cause equipment failure. The system’s heat exchanger cannot work unless there’s sufficient air moving across it to stop it from overheating. In short, a dirty blower can cause the heat exchanger to fail.
Why does my car only have heat when driving?
First check the engine coolant to make sure that its full. Top off the coolant if its low.

Why does my car heat up in the winter?
Reason #1: Not Enough Coolant. Your car uses coolant – usually made up of 50% antifreeze and 50% water – to cool your engine down, especially during the hot months of summer. During the winter when you crank up your heat, the coolant is brought over from the engine to the heater core that then blows warm air into your car.
Why is my car heater not blowing warm air?
A heater core is responsible for a vehicle’s defrosting and heating actions. Heater cores are typically situated directly in the back of dashboards. If your car is not blowing warm air into the cabin and the coolant level is fine, then you could have an issue with your heater core.
