The Kia Seltos AC not working is one of the common problems that many people face. But there are some simple solutions to this problem. We will help you to find out how to fix the Kia Seltos AC not working issue.

Common Fixes for Kia Seltos AC Not Working

When you start the Kia Seltos AC not working, there are many issues that can be caused by this problem. The Kia Seltos AC compressor may be damaged or old. You should have a check on the compressor to find out if it is working properly or not. It could also simply be dirty.

Clean the condenser

If your condenser is dirty, the easiest solution is to clean it. Using a power washer can also be useful. You can clean the condenser by removing the front bumper and accessing the inside of the unit. If your condenser fins are damaged, you can use a power washer to clean them. Just remember to set it to low pressure. High pressure can damage them.

It is possible to search for leaks in the air conditioning system by using a gas called ‘forming gas’, which is normally obtained in a garage. So we can check whether the low refrigerant supply is caused by a defective condenser. If this is the case, the only solution is to change the part. If this is the case, you have no other option but to use a new condenser.

Check the blend door actuator

Blend door actuator controls the airflow and temperature inside your Kia Seltos. If you are having problems with the air conditioning or the temperature, it could be the problem with the blend door actuator.

Most frequently, you will hear a slight clicking noise coming from under the dash. When you turn on the air conditioning or adjust the thermostat, the click sound that you hear will be loudest for a few seconds. Sometimes turning down the temperature will stop the sound temporarily.

Overcharged refrigerant

AC units in Seltos can warm up when overcharged with refrigerant. Being too much refrigerant in your system can cause damage to your compressor and cause a major leak

It is also possible to find out how high your vehicle’s refrigerant pressure is when the outside temperature is not as cold as recommended. You may need to check the owner’s manual or look under the hood of your vehicle to find out what type of refrigerant your vehicle uses.

Install a pressure gauge and a low pressure port in your car. If the pressure gauge shows that the pressure is higher than the pressure that is recommended, you should let some of the refrigerant out, preferably in a rag, in order to avoid damaging the compressor.
