If your heater isn't working then it could be an issuing with your coolant. Your coolant flows through your engine to keep it cool, but it also flows through your heater core. As your engine warms up your coolant flows from your radiator into your engine and then into your heater core. This is what creates the warm air inside your vehicle. When your coolant is low then there is not enough coolant to go around and your heater will not warm up properly. Once the leak is fixed and your coolant is topped off then your heater should work properly. Give us a call to schedule your appointment and let us take care of you.
