It’s a frosty morning and you’d like some toasty warm air. Yet, when you turn on your car’s heat, cold air blows from the vents. With wintertime approaching, you want to know if there’s a quick fix for no heat in your car.
Is There A Quick Fix For No Heat In A Car?
Sometimes, some car problems are easy to fix, like low coolant. When you’re experiencing problems with your car’s heating system, the first thing to check is your coolant level. Low coolant levels can interfere with the heat functioning properly.
When your engine is cool, pop your car’s hood and locate the coolant reservoir. On the side of the tank, you should see low and full-level markings. If the coolant is low, add some antifreeze to the reservoir tank until it reaches the maximum line.
While noting the level, also check the color of the coolant. Old coolant will have a muddy appearance and may have debris floating in it. Contaminants in your coolant can clog passageways in both the radiator and heater core.
In addition to causing overheating, old coolant can interfere with your car cabin heating. Performing a radiator flush will remove debris and replace your system with clean, fresh coolant:
- Drain the existing coolant from the engine. Plug and recap the radiator.
- Pour in a flush product according to the directions.
- Run the car for 10 minutes with the heater on.
- Allow the engine to cool and then drain it.
- Refill with water and run the car again for 10 minutes.
- When the engine is cool, drain and refill with clean antifreeze.
Typical Causes Of Broken Car Heater
Coolant issues are only one reason why your cabin won’t heat up on a frosty day. Several other parts can cause problems:
- Broken Thermostat
Many times, a broken thermostat is to blame when cold instead of warm air blows from your car’s vents. The thermostat’s function is to regulate the flow of coolant through your engine. When your engine is cold, the thermostat prevents coolant from entering the engine. This allows your engine to come to optimal operating temperature quickly.
As it fails, it may stay in the open position. If there is a continuous flow of coolant, the engine will run cooler than recommended. Thus, the coolant will fail to pick up significant heat to warm the cabin.
- Failing/Clogged Heater Core
The hot coolant passes through the heater core where it heats the surrounding air to warm the cabin. Similar to a radiator, your heater core is susceptible to clogs and corrosion. When it begins to fail, it may exhibit one of these signs:
- Overheating engine
- No heat in your cabin
- Sweet-smelling odor in the cabin
- Windows fogging
- Constant low coolant
- Air In The Cooling System
Air can enter your engine’s cooling system through leaks. With air in the system, the coolant won’t be able to absorb and release heat properly.
- Broken Blower Motor Fan
A fan blows air across the heater core, directing it into your cabin. If the motor breaks, you won’t experience any airflow from the vents. Sometimes the fix is an easy one like a blown fuse. Other times, it may require replacing the fan.
Quick Fix For Heat Not Working in Your Car- FAQs
Sometimes, you may find a quick fix for no heat in a car. Other times, it may be a more complicated and expensive repair. At Havoline® Xpress Lube of Kernersville, we can help you make the best decisions for maintaining your car. Below, we answer a few commonly asked questions about your cabin heat.
What Maintenance Do Manufacturers Recommend for My Car’s Heating System?
Primarily, flushing and replacing the coolant is an important step in maintaining the health of your car’s heating system. Many experts recommend performing this service every 3-5 years or 30,000 miles. Of course, check your vehicle owner’s manual for guidelines on your automobile.
Furthermore, a technician can inspect your system when you bring your car in for a state safety inspection. Doing so can help detect small leaks and problems before they become expensive repairs.
How Much Does Fixing A Car’s Heating System Cost?
Of course, without knowing the exact problem with your heater, we can’t quote you a price. For example, a thermostat replacement will cost a few hundred dollars, while a heater core replacement can average over $1000. In addition, the make, model, and year of your vehicle will impact your cost.

Can I Safely Drive With A Broken Heating System?
