Signs Your Car Heater Needs Repair

If your vehicle's heating system isn't working properly, you may notice one or more of these warning signs:

• Cold air blowing from the vents

• Heater only works at certain fan speeds
• Foggy windows that won't clear
• Sweet smell inside the vehicle

Frequently Asked Questions

Why is my car heater blowing cold air?

The most common causes include low coolant, a faulty thermostat, a clogged heater core, a failing blower motor, or problems within the cooling system.

Can low coolant cause my heater to stop working?

Yes. Your heater relies on hot engine coolant to produce warm air inside the cabin. Low coolant levels can reduce or eliminate heat.

Is my car heater connected to the cooling system?

Yes. Your vehicle's heater uses heat generated by the engine's cooling system. Problems with the radiator, thermostat, water pump, or coolant can affect heater performance.

Why does my heater smell sweet?

A sweet smell inside your vehicle may indicate coolant leaking from the heater core. This should be inspected promptly.

How often should my heating system be inspected?

It's a good idea to have your heating and cooling systems inspected at least once a year, especially before winter.

Do you repair heaters on all vehicle types?

Yes. We service the heating systems on most domestic and import cars, trucks, SUVs, and hybrids.
