Yes, the coolant temp sensor does affect the air conditioner. The two systems are interconnected, so if the coolant temp sensor is faulty or missing, then your a/c won’t work properly. The sensor monitors the coolant’s temperature and sends information to the computer about how much electricity to use for fan speeds and compressor operation.

Does engine coolant temperature sensor affect AC?
Air conditioning should be unaffected by changes in engine coolant temps.
What happens when the coolant temperature sensor goes out?
The computer may receive cold signals if the coolant temperature sensor malfunctions. Computers are tricked into over-enriching fuel mixtures when they perform actions like this. This can cause the fuel mixture to be volatile, resulting in a lack of efficient combustion in the combustion chamber.
Is engine coolant related to air conditioning?
As a heat transfer fluid, coolant is a component of the air conditioning system. A coolant circulates through your car’s engine, preventing the cylinders from overheating by keeping them lubricated.
How do I know if my AC temperature sensor is bad?
The majority of HVAC service providers will tell you that a faulty sensor is to blame if your system runs inefficiently or fails to turn on at all. If this occurs, you may experience sudden changes in your home’s temperature and find yourself in an uncomfortable situation.
Can low coolant cause my AC not to work?
Air conditioning systems use a chemical called coolant, or freon, to lower temperatures. This chemical will eventually run out if there is a leak in the system. Modern air conditioning systems are much more delicate than older models. Without enough of this chemical, the air conditioner will not function properly.
Does a car thermostat affect AC?
The A/C compressor should not be affected by the thermostat. It is the thermostat’s job to keep the engine cool and regulate the amount of coolant flowing into and out of the engine from the radiator by opening and closing at predetermined temperatures.
Does the coolant temp sensor control the fan?
In response to the CTS temperature reading, the control system can either turn off or turn on the cooling fan. It could also mean that a richer fuel mixture is needed, or that the exhaust gas recirculation should be opened.
Do you need to drain coolant to change coolant temperature sensor?
Changing a coolant temperature sensor does not necessitate draining the coolant. A couple of quarts of coolant can be removed by opening the radiator valve. It is only necessary to remove enough to bring the water level below the sensor’s sensor.
Why is my AC not blowing cold air in my car?
Recharging the air conditioning system is the most common cause of a vehicle’s air conditioner not working as well as it should. In order to save time and ensure that the job is done correctly, you should make an appointment with your local professional auto shop to recharge your refrigerant.
Why is car AC not cold?
If your air conditioner isn’t getting cold enough, the most likely culprit is a depleted supply of refrigerant. Only a Freon leak in the AC system could explain why the system needs to be recharged. Automotive air conditioning systems are pressurized and sealed, making them vulnerable to leaks.
