Why Did My Car Heater Stop Working?

The most common fix for a car heater blower not working is a heater motor replacement. In some cases the problem can stem from under the hood. Other related causes if your heats not working include:

  • Coolant leak: low coolant supply to the heater core will result in no heat in your car, truck or SUV

  • Heater core repair: a small radiator that controls coolant flow for heat inside the cabin

  • Heater blower motor: no heat blowing inside the cabin

  • Radiator problem: a radiator repair or recore of may correct a no heat problem

  • Faulty HVAC controls and valves: small parts in the car's heating & AC system that can fail

  • Thermostat problem: a stuck or faulty thermostat will not enable the heat to kick in

If your vehicle is warmed up and the vents are blowing cold air, the problem is likely your heater or engine coolant. Your car's heating system uses coolant (antifreeze) from the radiator. If coolant is low and there's not enough to supply both the engine and the heating system, the engine takes precedence. A more serious problem when your heat is not working is the water pump. The water pump is responsible for circulating coolant throughout the engine and radiator, if the problem is the pump, coolant runs through the engine rather than the heating system.

Your car's heater blower is the main electric motor responsible for blowing both hot and cold air out of the vents. If it no longer works or stopped working at certain speeds the problem is likely a heater blower motor repair. Aside from the discomfort, you might also notice the window defogger stopped working among other issues such as fogged windows and antifreeze smell inside the cabin. Fortunately, if it's a heater blower motor replacement, there are a few signs we describe below that let you know it's time for a repair.

Can a Heater Core Be Repaired or Needs Replacing?

Typically, deep underneath your dashboard and firewall, lives your car's heater core. If a heater core has gone bad, it may be possible to repair but highly likely needs a replacement. In either case, a heater core repair requires removing the inner dashboard of your vehicle to access and is a complex and intense job. As such, when we replace a heater core it's also a good idea to replace the heater hoses attached to it.

A future problem with heater hoses will create similar problems to that of a heater core replacement and we want to ensure the job is only done once. As part of the replacement job, certain vehicles will need to have the air conditioning system rechargedOnce we've inspected and diagnosed a heater core repair problem, we will advise whether this is required as a part of the heater core job for your vehicle.

Is a Heater Core Replacement Necessary?

If time or money is something you can't spend at the moment, another option for heater core repair is to disconnect the heater hoses connected to the heater core. This will save on a replacement cost but the labor involved would make a replacement worth it. Plus, bypassing the heater core will leave you without heat or a defroster. For these reasons, fixing a heater core once and for all is the most cost effective solution if you plan on keeping the vehicle for a while.

A heater core function is part of the cooling system. Engine coolant circulates through the engine and passes through the heater core which provides the heat inside the cabin. As you use your car heater, the blower fan sends warm air from the vents heating the interior and defrosting your windshield. When your vehicle's heating is functioning properly, you're in control of the heat. However, when a heater core problem develops, control is lost and there are very noticeable signs we'll describe below that suggest it is indeed a heater core replacement to gain back control and heating in your car, truck or SUV.


Car Thermostat Replacement

Here are a few symptoms you might notice if your car thermostat needs replacement. The symptoms of a faulty car thermostat can include:

  • Overheating engine: If your car's temperature gauge indicates that the engine is running hot or the engine overheats, it could be a sign of a bad thermostat.

  • Poor performance: A faulty thermostat can cause poor engine performance, including reduced acceleration, poor fuel efficiency, and rough idling.

  • Cold engine: If the engine takes a long time to warm up or never gets warm at all, it could be due to a stuck-open thermostat that's preventing the engine from reaching its optimal operating temperature.

  • Coolant leaks: A faulty thermostat can cause coolant leaks, which can be identified by puddles of coolant underneath the car or a sweet-smelling liquid on the engine block.

If you suspect that your car's thermostat needs to be replaced, stop by our shop for inspection and repair by our qualified mechanic as soon as possible to prevent further damage to the engine.


Heater Core Replacement

There are several symptoms that may indicate the need for a heater core replacement. These symptoms include:

  • No heat: If you're not getting any heat from your car's heater, it may be due to a faulty heater core. This is because the heater core is responsible for heating the air that comes through the vents.

  • Poor heat: If you're getting some heat, but it's not as warm as it used to be, it may be due to a partially clogged or leaking heater core.

  • Sweet smell: If you notice a sweet smell in the cabin of your car, it may be due to a leaking heater core. The sweet smell is caused by the coolant leaking from the heater core.

  • Foggy windows: If your windows are fogging up, even when the defrost is on, it may be due to a faulty heater core. This is because the heater core helps to remove moisture from the air.

If you are experiencing any of these symptoms, it is important to have your car inspected by our local mechanic as soon as possible. Ignoring a faulty heater core can lead to more serious problems down the line. The heating system is a closed loop; fresh water from the radiator cools off an electric pump and it gets sent through your heater core to be heated up before being sent out through your vents. This means if you have bad flow in this system, there is no way for the water to get hot enough to heat your car or in some cases, they can't get heated at all.

Our heater core repair process involves taking out your interior heater core box, removing the old heater core and installing the new one. We know that this can be a tough job because it requires taking apart most of the front end of your car to get to the inside of the heater box. But our process is quick and efficient so you don't have to worry about being without your heat during the cold season.
