Frequently Asked Questions For Why Is My Heater Not Working In My Car

Why is my car releasing cold air while the heater is on?

A possible reason why your car is blowing out cold air when the heat is on is due to low coolant levels. When there isn’t enough coolant in the system, the heater core will not be able to produce warm air.

To fix this, you will need to top off your coolant and check for any leaks.
