Why does my heater only work when I accelerating?
It’s caused when your coolant gets low. Fix your leak and bleed the coolant system. Or you can check this theory by filling and bleeding the coolant system now. If it works, it will be ok until the coolant system gets low and causes the air bubble again.
Why does my car’s heater blows cold air when stopped?
Hot coolant from the engine passes through a heater core, which looks and functions a lot like a small radiator, and a blower motor forces air through it. It’s also the reason that a plugged heater core, stuck thermostat, or air in the cooling system can all cause a car’s heater to blow cold.

A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn’t allowing the engine to properly warm up. A blower fan that isn’t working properly.
