What else can I help you with?
Why would heater blow warm air while driving but cold air while idling and why would enigine temperature go up while idling and down when driving?
When a vehicle is idling, the engine may not produce enough heat to warm the coolant effectively, leading to cold air from the heater. In contrast, while driving, the engine works harder and generates more heat, allowing the heater to blow warm air. The engine temperature can rise while idling due to reduced airflow through the radiator and less coolant circulation, while driving increases airflow and coolant flow, helping to cool the engine.

What would cause car to over-heat after idling for 15 minutes?
It could be a variety of things, all having to do with the cooling system. Most likely it is a faulty engine fan that is supposed to automatically cut on when your engine hits a certain temp. It could the the fan motor itself, the relay that controls the fan, and maybe just a fuse. If the car does not overheat AT ALL in freeway driving (lots of cool air passing over the engine constantly) and overheats either idling or during city driving that engine fan is to blame.
