Why Is Your Car Heater Failing?
A malfunctioning heater often stems from coolant leaks, which reduce warmth and risk engine overheating. Low refrigerant levels, a stuck thermostat, or a clogged heater core (responsible for 40% of failures) are other culprits. Electrical faults in blower motors or control panels may also trigger cold air. Ignoring odd smells or weak airflow can lead to costly repairs—like a $300–$800 heater core replacement.
Signs You Need Immediate Repair
| Symptom | Likely Cause | Estimated Cost |
|---|---|---|
| Cold air only | Low coolant, stuck thermostat | $100–$250 |
| Sweet smell | Heater core leak | $400–$800 |
| Clicking noises | Blower motor failure | $150–$300 |

FAQ
How long does car heater repair take?
Most fixes (thermostats, blowers) take 1–2 hours. Heater core replacements may require 4+ hours due to dashboard removal.
Can I drive with a broken heater?
Yes, but not recommended. Cold cabins reduce visibility (frosted windows), and coolant leaks may lead to engine damage.
Why does my heater work but not the defroster?
Often a blend door actuator issue. This $75–$150 part directs air to windows.
