What’s Wrong With My Car’s Heater? Common Problems & Quick Fixes

🔧 Common Car Heater Problems
1. Low or Leaking Coolant
Your heater relies on hot coolant from the engine. If your coolant level is low or there’s a leak, your heater can’t produce warm air.
What to check: Look under the car for green or orange puddles, or check the coolant reservoir.
2. Faulty Thermostat
If your engine isn’t warming up properly, the thermostat might be stuck open—preventing hot coolant from reaching the heater core.
Signs: Temperature gauge stays cold even after 15+ minutes of driving.
3. Clogged Heater Core
The heater core acts like a small radiator inside your car. Over time, it can get clogged with rust, debris, or old coolant.
Signs: Weak airflow, foggy windows, or a sweet smell inside the car (from leaking coolant).
4. Blower Motor or Fan Issues
If warm air isn’t blowing at all, the problem might be the blower motor, resistor, or fan controls.
Symptoms: No air coming out, only working on high speed, or unusual noises from the vents.
5. Air Pockets in the Cooling System
After coolant service or a leak, trapped air can prevent proper coolant circulation.
Fix: The system needs to be properly “bled” to remove air pockets.
