If your car heater is blowing cold air, there are several possible causes to consider. Identifying and addressing the issue promptly can help ensure a comfortable driving experience.
Why does my car make a clicking noise when accelerating?
The presence of a clicking sound can indicate that the valves are not opening and closing properly in terms of timing and distance. The cylinder head of an engine employs various lifters to perform this function. Over time, these lifters can wear out, resulting in a metallic ticking noise occurring both when the engine is idle and when it is accelerating.
If you are experiencing a ticking or clicking noise in your engine, there are several potential causes and solutions that can address this issue.
Does the clicking noise in my car heater indicate a faulty blower motor?
Blower motors often experience frequent failures due to the heavy workload they endure. Early signs of a failing blower motor include slow starting, intermittent operation, and squeaking noises. The causes of these failures often include blocked windshield cowl drains that allow rainwater to enter the heater assembly and damage to the motor windings.
If you notice loud noises when using your car's heater or air conditioner, it is likely that there is an issue with the blower motor. Fortunately, in many cases, such problems can be easily resolved by removing debris or trash that has become stuck in the motor.

How do I know if my heater blower motor is bad?
One of the initial signs of a possible issue with the vehicle's heater blower motor is a weak airflow from the vents. If the air or heat is turned on and the vents are blowing noticeably less or weaker air, it could indicate that the heater blower motor is beginning to deteriorate.
Why is my blower motor not working?
If the blower motor in your vehicle is unable to switch between high and low settings, one possible cause could be a malfunctioning resistor. The blower motor resistor is responsible for regulating the speed at which the fan operates. When this component fails or experiences a short circuit, it can result in the blower motor becoming stuck. As a result, you may still be able to receive the desired temperature, but you will not have the ability to adjust the speed accordingly.
If you suspect that your blower motor resistor is faulty, there are a few signs to look out for. These include the inability to switch between high and low settings, the fan only working at one speed, the fan not working at all, or the fan getting stuck at a particular speed. If any of these symptoms are present, it is recommended to have the blower motor resistor replaced. To determine the exact cost of replacement, it is best to consult with a qualified mechanic.
What are the symptoms of a faulty blower motor resistor?
A common symptom of a malfunctioning blower motor resistor is when the blower motor remains stuck on a single setting. The blower motor resistor is specifically responsible for controlling the fan speed of the blower motor. In the event of a short or failure of the resistor, the blower motor may become permanently stuck on one fan speed.
If you are experiencing issues such as these, it is likely due to a faulty heater blower motor resistor.
Why is my car heater not blowing air?
If the car heater is not blowing any air, the most probable cause could be a defective blower motor or an electrical connection issue.
To address this problem, follow these instructions to diagnose and resolve issues with a car heating system that only blows cold air. However, if the heater is not blowing any air at all, please skip to the next section.
Begin by checking the coolant level. Ensure that the vehicle is turned off and allow the engine to cool completely before proceeding with any further troubleshooting steps.
Will replacing the heater core fix the clicking noise in my car heater?
When troubleshooting your car's heater not working, there are a few potential solutions.

How do I know if my car has a heater core problem?
If you are facing a heater core problem, there are certain indications that can help you identify the issue. One of the signs is when there is a lack of heat inside your car. Despite your vehicle running smoothly and having no other cooling system issues, the heat never seems to warm up.
Symptoms of a failing or damaged heater core include a lack of heat inside the car. This occurs even when the vehicle is functioning normally with a temperature gauge reading within the normal range. Despite this, the heat does not warm up when turned on.
When experiencing a heater core problem, one common sign is the absence of heat inside the car. Even though the vehicle is operating without any other cooling system complications and the temperature gauge displays normal readings, the heat fails to warm up.
How does a car heater work?
The heater core is a component that is situated in the passenger side compartment of the car, specifically underneath the dashboard. It receives coolant from the engine and utilizes a blower motor to circulate air across the heated coolant. As a result, the air absorbs the heat from the coolant and is then distributed through the heater vents, providing warm air to the cabin.
If you are in need of heater core replacement service, you can rely on professionals to handle this task for you. The cost of such a service will depend on various factors, such as the make and model of your vehicle, as well as the specific circumstances surrounding the replacement.
How do you remove a heater from a car?
To replace a heater core, start by disconnecting the two heater inlet/outlet hoses at the firewall. Remember to plug all open lines and fittings to prevent contamination of the cooling system. You may need to remove the air conditioning accumulator depending on the model. Next, remove the temperature blend door actuator and disconnect any remaining electrical connectors. Finally, remove the plastic heater core cover.
Can low coolant levels contribute to the clicking noise in my car heater?
When the coolant level in the coolant system is insufficient, it primarily affects the heater core upon engine shutdown. As a result, upon restarting the engine, the void left by the low coolant level is filled with air, resulting in a gurgling noise. This occurrence can be attributed to the formation of an air pocket within the system.

Driving with low engine coolant can have various causes and consequences, which should not be neglected. It is important to address this issue promptly to avoid potential damage to the engine or overheating, which may result in more severe and costly repairs
Can a low coolant cause a hot engine?
A significant portion of the heat generated by the engine needs to be regulated through a different method. An important fluid known as antifreeze or engine coolant plays a crucial role in maintaining the engine's ideal operating temperature. However, driving with a low level of coolant can potentially cause severe issues for your engine, vehicle, and overall journey.
Why does my car make a rattling noise?
One common issue that can cause low coolant levels is a coolant leak. This can be identified by the presence of coolant puddles underneath the vehicle or a noticeable sweet, pungent smell emanating from the engine compartment.
Another symptom of low coolant is increased engine noise. When there isn't enough coolant, the engine may produce a rattling or grinding noise due to heightened friction and wear.
If you are experiencing low coolant symptoms, it is important to address the issue promptly.
Should I seek professional help to address the clicking noise in my car heater?
Experiencing a clicking noise in your car heater is an indication of a problem that should not be ignored. This noise could potentially be attributed to a faulty blend door actuator, malfunctioning compressor, or a worn-out clutch.
If the clicking noise persists continuously, it would be advisable to take your car to a qualified mechanic for a thorough inspection and appropriate repairs. Additionally, occasional bangs or booms may emanate from the ductwork, vents, and metal components as the heater turns on and off, which is typically considered a normal occurrence in many cases.
