Car AC Blowing 50 Degrees – Fix Right Now In 2023

Nothing is more annoying than turning on your car’s air conditioning system on a hot summer day only to discover that it is pumping out heated air at about 50 degrees Fahrenheit instead of cool and refreshing air. Driving in such a situation might be uncomfortable, and you can wonder what’s wrong. 

Bad Fan Motor on the condenser/radiator, blocked condenser, dirty air filter, leaking refrigerant, electrical issues, and high temperature are the causes of car ac blowing 50 degrees.

In this post, we’ll examine the possible reasons why your car’s air conditioner is only blowing air that’s 50 degrees and go through what you can do to repair the problem.

Why Does Car AC Blowing 50 Degrees? Let’s Discuss Its Causes And Solutions:

1. Bad Fan Motor On Condenser/Radiator: 

When it comes to distributing heat from the condenser and radiator, the fan motor is essential. Warm air may stream through the AC vents, and insufficient cooling may result from the fan motor not working as it should and blowing 50 degrees.

Check the fan motor first if the air conditioning in your automobile can’t cool the inside below 50 degrees. The condenser, often housed in the engine compartment, contains the fan motor. Set the AC to the coldest setting and turn it on to do this. The condenser fan should then be checked in the engine compartment. If it isn’t moving, the fan motor may be malfunctioning.

If you want to do things yourself, you can do this test or call a specialist known as an electromechanical technician to examine the fan motor’s connections for continuity. Next, check to determine if the condenser is blocked and the fan motor appears to be in good condition. It ensures that there is adequate airflow for cooling.

2. Blocked Condenser: 

The condenser’s function is to allow the refrigerant to cool down by releasing heat from it. A blocked or obstructed condenser does not effectively dissipate heat, resulting in warmer air from the AC system.

Cleaning the radiator and condenser parts will help to resolve this issue. Clean the condenser’s fins using a soft brush or compressed air. Remove any dirt, leaves, or debris obstructing adequate ventilation. Bring your automobile to an engine car wash so professionals can completely clean the engine radiator area. If the condenser and radiator fans appear in good condition, but your car’s air conditioner is still blowing 50-degree air, it may be because the air filter is unclean. 

3. Dirty Air Filter:

The efficiency of the AC system is decreased, and warmer air is blown when a blocked or dirty cabin air filter constrains the airflow into the cabin.

A typical cause of inadequately cooling automotive air conditioning is dirty air filters. These filters should be replaced every two to three months and are typically found in the engine or bonnet compartment.

If you drive a lot, you might want to change it every 2000–3000 miles. These filters are reasonably priced, frequently running around $10. If the air filter isn’t the issue, though, it’s possible that your car’s air conditioning system may not have enough refrigerant.

4. Leaking Refrigerant: 

Your air conditioning system’s vital component, refrigerant, cools the air. Leaks in the system cause the refrigerant level to fall, which causes inefficient cooling and warmer air to be blown into the cabin.

A refrigerant leak may be to blame if your car’s air conditioner won’t drop below 50 degrees. You can search for leaks to determine this. However, even professionals may find it challenging at times. We should be patient.

Verify for leaks that appear green and oily if the refrigerant is low. You can recharge your air conditioner after finding and fixing any leaks. Recharging won’t help because the refrigerant will continue to leak out of the system even if no leaks are discovered.

5. Electrical Issue/Blown Fuses: 

For proper operation, modern AC systems need electrical parts, including fuses. Warm air can come from an AC system interruption caused by a blown fuse or a bad electrical connection.

Blown fuses may be to blame if the air conditioning in your automobile is blowing 50-degree air. To determine this, you can use a digital voltmeter or a basic, low-cost 12V test light. Make sure the electrical connections are tidy and securely fastened as well.

6. High Temperature: 

IF IT IS HOT OUTDOORS, the AC system may have trouble adequately cooling the air before entering the cabin, resulting in warmer air flowing through the vents.

An extremely hot interior may impact the cooling ability of the air conditioner. Car air conditioners typically have a 30-35 degree cooling capacity. Therefore, the AC may blow 45–50 degrees air if the cabin temperature is between 80–85 degrees. The AC can deliver cooler air when the cabin temperature drops.


1. What Temperature Should Come Out Of Car AC Vents?

Use a precise thermometer to measure the outlet temperature at the vent to determine how well your air conditioning system is working. Activate the A/C on “max” when driving. The outlet temperature should be between 35 and 48 degrees, with temperatures in the 70s to 80s Fahrenheit.

2. Are 50 Degrees Good For AC?

HVAC manufacturers (heating, ventilation, and air conditioning) systems advise consumers not to switch on their air conditioning when the outside temperature is below 59 degrees Fahrenheit. Running the machine when it is cold can harm it. If this occurs, the situation can worsen as the temperature rises.

3. Is It Bad To Run AC At 60 Degrees?

Your air conditioner will suffer if the thermostat is kept at a very low setting. Setting your thermostat between 60 and 67 degrees will prevent less heat exchange through the evaporator coil, preventing your evaporator from successfully preventing freezing.

4. Why Is My AC Blowing Cold But Not Cold Enough?

There may be a leak in the house leading to the outside if the air conditioner is pumping cold air but not cooling the indoors. Verify that every window and entrance is shut. It may not be the desired temperature and may only be the fan blowing if the air feels colder than the ambient temperature.


Understanding these typical reasons and their cures can give you the confidence you need to handle the situation when the air conditioner in your car is blowing air that is anything but refreshing. Regular maintenance, prompt replacements, and professional inspections ensure your car’s air conditioning system performs at its peak, providing cool and comfortable rides even on the hottest days. Remember that hiring a qualified mechanic is always a smart move to ensure efficient and secure repairs if you need clarification on diagnosing or fixing the problem yourself.
