On the other hand, if you discover a possible coolant leak, have a mechanic find and fix the problem as soon as possible. If you drive in cold weather, your car's heater is invaluable. In order to appreciate why problems develop, it's worth reviewing how your vehicle's heater works. If you're using your vehicle's air conditioner, the valve will remain closed. But it's important to identify the reason your heater is unable to produce warm air. The heat that is blown through your vents originates within your engine. Given the process described above, it should now be clear that problems affecting your car's heater are usually due to issues within the cooling system. Check The Blower Motor The next component to inspect is the blower motor. But be aware the low level may imply a leak somewhere in the system. Problems that occur with the blower motor can include accumulated debris that jams the system, a blown fuse, or a failing switch. This is the small fan that blows across the heater core, pushing hot air through your vents. Check The Control Valve The flow of coolant to your car's heater core is controlled by a component called the heater control valve. Basics Of Your Vehicle's Cooling System Your engine creates enormous heat during operation. Your vehicle should have a separate, clear coolant reservoir through which you can see the fluid level. The coolant arrives at your heater core after absorbing this heat.e. If it fails, it cannot blow heated air into the cabin, regardless of whether coolant has entered the heater core. The heater core is rarely discussed.. Your radiator is located near the front of your car. Coolant flows through a network of hoses to your engine in order to absorb excess heat. Otherwise, the valve remains open. Another component called the heater core functions like a tiny radiator near the back. malfunctioning control valve or failing blower motor), repairs can wait. Hot coolant flows to the heater core
China Electric Motors Suppliers where a small fan operates. That's where we'll begin troubleshooting. when your engine is running). Check The Coolant Level Because your heater core operates based on the coolant that travels through it, an insufficient fluid level will impair its function. Driving in cold climates without heat can be a miserable experience. In this position, coolant will not enter the heater core and thus, heat will not enter your car's cabin. In fact, millions of drivers are unaware it exists. All circumstances lead to the same result: the hot air cannot be blown through the vents. If the vents in your vehicle's cabin are open, the fan blows heated air from the hot coolant through them. The other marker identifies the appropriate level when the fluid is cold. Coolant leaks can worsen and cause your engine to overheat. If the problem is specific to the heater core (i. If this heat were allowed to remain near the engine, it would destroy the assembly. The coolant, cool again, flows back to the engine to absorb more heat. If the heater control valve malfunctions and remains closed when it should stay open, it will prevent coolant from entering the heater core. This can lead to expensive damage that is entirely avoidable. Your vehicle's cooling system addresses this problem.e. It then travels to your radiator, where the heat is allowed to dissipate into the air. One of these markers identifies where the fluid should be when it is heated (i. Because the fluid cannot gain entry, there is no heat that can be blown through the vents into the cabin of your car. It is located in the dashboard. But if it fails, it can have far-reaching impacts, especially in cold weather. That requires taking a look at the cooling system. Unfortunately, like all components and systems, it can fail for a number of reasons. If the level is low, remove the radiator cap and add more. There should be two markers on the reservoir.
