The most likely reason 2017 Hyundai Tucson heater is blowing cold air is a lack of coolant in the system.

2017 Hyundai Tucson Heater Blowing Cold Air

The 2017 Hyundai Tucson Heater was designed to keep you warm in colder temperatures. However, some owners have reported that they are having problems with their heater blowing cold air instead of warm air. This can be caused by a few different factors and troubleshooting steps can vary depending on the issue. Common causes include a faulty thermostat, a clogged heater core, or a low coolant level. Additionally, the coolant should always be filled with proper anti-freeze to avoid freezing in cold temperatures. If your Tucson’s heater is blowing cold air and a relatively straightforward issue such as this is not to blame, then it may be time to take it into a Hyundai dealership or other automotive service center for further diagnosis.

Engine Coolant Level

It is important to ensure that your engine coolant level is at the right level as it is vital for your cars overall performance. Low engine coolant levels can cause your engine to overheat and can lead to serious damage. Symptoms of low engine coolant levels include the temperature gauge reading higher than usual, steam or smoke coming out of the radiator cap, a loud boiling or hissing sound coming from the engine, and an increase in the temperature around the engine bay. To check and refill your engine coolant, you will need to open the radiator cap and look down into the radiator to check for any signs of low fluid levels. If it is necessary, you can top up the level with a mixture of water and antifreeze.

Air Filter Cleaning and Replacement

Having a blocked or dirty air filter can reduce the performance of your car’s engine, as it restricts airflow into the engine which increases fuel consumption and reduces power. To check if your air filter needs cleaning or replacing, you should open up the air box and remove the filter housing lid. Inspect both sides of the filter for any signs of dirt or blockages, if it looks dirty then you should replace it with a new one. The difference between a clean and blocked performance air filter lies in their ability to allow air through them efficiently; with a clean filter allowing more air through than a blocked one will.

Radiator and Hoses Inspection

Your car’s radiator is responsible for ensuring that your car runs at optimal temperatures by cooling off hot fluids from within your engine; therefore it is important that it functions correctly. Signs of radiator issues include visible leaks from hoses or from underneath your car, as well as puddles forming underneath your car when parked up overnight. It is recommended that you inspect both your radiator and hoses on a regular basis for any signs of wear or damage; this can be done by simply opening up your hood and inspecting them visually for any signs of leakage or damage.

Pressure Test The Cooling System

A pressure test on your cooling system involves using specialised tools to pressurise all components of your system such as hoses, radiators, thermostats etc., in order to identify weak points where pressure could be leaking out; this could indicate potential problems such as blockages or cracks in these components which need addressing before they become worse over time. There are different levels of pressure tests available depending upon how deep you want to inspect these components; however each pressure test comes with its own set of pros and cons depending upon what they involve.

Heater Core Clogging

Heater core clogging can be caused by various factors such as sludge build-up over time due to lack of maintenance or rust particles entering into your system from old pipes/fittings etc.. If you suspect that there may be clogging issues with your heater core then firstly it is important to diagnose what might be causing them before attempting any remedial work yourself; this typically involves performing an inspection on both sides of the heater core visually looking for blockages/debris etc.. Once identified then steps need taking in order to unclog these issues; this typically involves using flush solutions either by flushing out via chemical cleaners or by using compressed air depending upon what type issue has been identified initially during diagnosis stage. Advantages/disadvantages exist when using flush solutions such as cost versus effectiveness so care should be taken when selecting one suitable for purpose.

Cooling Fan Problems

Having a faulty cooling fan in your 2017 Hyundai Tucson can be a major problem, causing your heater to blow cold air. There are a few signs that you may have a failing cooling fan including the fan not turning on or having loud noise when it is running. If the cooling fan needs to be replaced, the best alternative would be to purchase an OEM part that is specifically designed for your vehicle.

Thermostat Troubleshooting

If your 2017 Hyundai Tucson is not providing sufficient heat, thermostat troubleshooting may be necessary. One of the most common problems with thermostats is that they are not set correctly, so make sure to check the settings before replacing it. If this does not work, then it may be time to replace the thermostat altogether. When replacing the thermostat, make sure it is compatible with your vehicle and also properly installed by a certified mechanic or technician.

Leaking Seals or Gaskets Inspection

Leaking seals and gaskets can cause your 2017 Hyundai Tucson heater to blow cold air. The main signs of leaking seals and gaskets include oil or coolant leaks under the car as well as visible damage around gasket areas. To inspect and replace leaking seals and gaskets, you should start by diagnosing where the leak is coming from using a pressure gauge or vacuum tester. Then use some sealant or tape around any visible cracks or damage in order to prevent further leakage. Finally, use new OEM gaskets and/or seals in order to properly seal up any openings in order to prevent further leaks and maintain proper heating system performance.

Air Handling System Troubleshooting

If you are having issues with your 2017 Hyundai Tucson air handling system, troubleshooting may be necessary in order to diagnose mechanical issues in the ventilation system. The first step should involve inspecting all of the vents for any visible signs of damage such as dust buildup or blockages due to debris buildup inside of them. If any damage is found, it should be repaired as soon as possible in order to prevent further issues from occurring with your air handling system. Additionally, if any AC vents are blocked off due to furniture placement or other obstructions then these should also be cleared away in order for proper airflow throughout the vehicle’s interior cabin space.

FAQ & Answers

Q: What are the signs of low engine coolant?
A: Signs of low engine coolant include an overheating engine, gurgling noises from the radiator, and temperature gauge readings that rise and fall.

Q: How do I check and refill the engine coolant?
A: To check and refill the engine coolant, first turn off the vehicle’s engine and allow it to cool for at least 30 minutes. Then take off the radiator cap and use a dipstick to measure the level of coolant. If needed, add a 50/50 mix of water and antifreeze to bring the level up to the full line on the dipstick.

Q: What are signs of a blocked or dirty air filter?
A: Signs of a blocked or dirty air filter include poor fuel economy, increased emissions, reduced acceleration power, an illuminated check engine light, and decreased airflow into the cabin.

Q: What are advantages/disadvantages of using flush solutions to unclog heater cores?
A: The advantages of using flush solutions to unclog heater cores include that they are easy to use, cost-effective, and can dissolve mineral deposits more quickly than other methods. The disadvantages are that some solutions may contain harsh chemicals that could damage other components in your vehicle. Additionally, flushes don’t always clear clogs completely.

Q: What are signs of leaking seals or gaskets?
A: Signs of leaking seals or gaskets include oil or coolant leaks beneath your vehicle, smoke from under your hood, grinding noises when turning corners or accelerating, and decreased performance from your brakes or steering system.

The 2017 Hyundai Tucson has a complex heating system that is prone to malfunctions. If your heater is blowing cold air, it’s likely due to a faulty thermostat, low coolant levels, a blockage in the air intake system, or a problem with the blower motor. It’s best to take your vehicle to an experienced mechanic for an accurate diagnosis and repair.
