What Causes Car Heater Problems?
There’s more to your car heater than just a blower fan. Here’s what might be behind the problem:
- Faulty Thermostat: A broken thermostat may prevent your engine from reaching the right temperature, leaving your heater cold.
- Clogged Heater Core: Dirt or rust in the coolant system can block the heater core.
- Low Coolant Levels: Insufficient coolant may stop warm air from reaching your cabin.
- Heater Control Valve Malfunction: This valve controls the flow of hot coolant to the heater core.
- Blower Motor Issues: If the motor fails, air can’t circulate through the vents.
- Electrical or Control Problems: Faulty switches, relays, or fuses may stop your heater from turning on altogether.

Frequently Asked Questions (FAQs) About Car Heater Service
1. Why is my car heater blowing cold air?
This could be caused by low coolant, a faulty thermostat, or a clogged heater core. A diagnostic test can pinpoint the issue.
2. How much does car heater repair cost in Alpharetta?
It depends on the problem. A thermostat replacement may cost $100–$300, while a heater core replacement can run $600 or more.
3. Can low coolant affect the heater?
Yes! Your car heater relies on hot coolant. If levels are low, the heater won’t blow warm air.
4. How do I know if my heater core is bad?
Signs include sweet-smelling odors, fog inside windows, or coolant leaks inside the cabin.
5. Is it safe to drive without a working heater?
It’s not recommended, especially in cold weather. A faulty heater may also signal coolant problems that could damage your engine.
6. How often should I flush my heater core?
We recommend flushing the coolant system every 2–3 years to prevent buildup and corrosion.

We specialize in Japanese and Asian imports but service all makes and models.

Absolutely. We replace or repair blower motors as part of our car heater services.
