Winters in upstate New York are long and cold. To stay comfortable during your daily commute, you rely on your car’s heating system. However, when a malfunction occurs, it’s important to diagnose the problem so you can seek an immediate solution. Below are a few of the most common reasons a car heater might not be working and when to seek professional auto repairs.

Why Isn’t My Car’s Heater Working?

1. Malfunctioning Thermostat

The thermostat sends the signal for the coolant system to move heat from the engine to the heater core. If the thermostat gauge is stuck on “C,” this is a sign of a faulty thermostat; if it’s unable to alert the coolant system, your heater will only blow out cool air. An auto repair technician must replace the thermostat to restore your car heater to working condition. 

2. Water Leak

Coolant is typically a mix of water and antifreeze, which gets warmed by the engine and sent to the heater core, which passes it on as warm air. Insufficient amounts of water or antifreeze will impede this process, so check the water pump, radiator, and hoses for any signs of a hole or leaking water.

3. Broken Heater Core

The heater core is responsible for dispersing heat from the coolant system throughout your vehicle. If your coolant level is sufficient, the problem may lie with your heater core. Some of the tell-tale signs include fogging inside of your vehicle or a musty odor coming from the vents.
