My car blows cool air while idle when heat is on but blows warm air while moving. What's causing this?

Hi,
Have you checked the coolant level? It sounds like you may be low on antifreeze.
Do me a favor. Allow the engine to completely cool off. Once it has, open the hood and locate the coolant reservoir. Make sure the engine is cool and open the reservoir cap to check if the coolant is low.
Let me know what you find. Also, I attached a pic below showing the reservoir. It shows unbolting it because it came from directions for replacement. However, that isn't what we are doing. It's just to help you locate it.
Let me know what you find.
Take care,
joe
