A. Cold air from your heater is normal for the first few minutes of operation. If the air from your vents doesn't heat up shortly, you've got a problem with your heater or your coolant. Your heating system borrows coolant (water + antifreeze) from the engine radiator, so if there isn't enough coolant for both systems, the engine gets the available coolant. Another possible culprit: your engine's water pump is failing to recirculate coolant back to the radiator -- again leading to a coolant shortage for the heater.

A. The heater core is a small, radiator-like device that usually sits behind your dashboard vents. Coolant enters the core, takes in heat, and then exits to warm up the air being blown into your cabin. Here are some common signs that your vehicle's heater core needs service:
- Your heater blows cold air: A punctured or otherwise damaged heater core can prevent heat transfer.
- Your cabin fogs up, after warming up: Coolant running through a bad heater core stays cold. The air blowing into your cabin cools down. If your cabin is already warm, condensation accumulates on all your windows.
- Your car smells sweet or bitter: If your heater core leaks, you may notice the fruity or bitter odor of coolant in your cabin or outside the vehicle. You may also have a radiator leak.
- Your coolant level drops: Another sign of a coolant leak in your heater core or radiator. Be alert to the risk of overheating.
- Your vehicle overheats: A blocked heater core can overheat your engine and strand you on the road.
