Have you ever experienced that your auto air conditioning gets warm when you are just idling but then cold when you are driving? This is a common issue among car owners and can be caused by a variety of factors. In this article, we’ll take a look at why your auto air conditioning gets warm when you’re idling but then cold while you’re driving and what you can do to fix it.
The most common cause of this issue is that the air conditioning system is not getting enough air. When you’re idling, the air conditioner is not getting enough air to cool the air inside the car. This is because the car is not moving and the air is not being circulated properly. As a result, the air conditioner gets warm and the temperature inside the car rises. On the other hand, when you’re driving, the air is being circulated more efficiently and the air conditioner gets enough air to cool the air inside the car.
Another cause of this issue is a dirty air filter. A dirty air filter can restrict the amount of air that the air conditioner is getting, thus making it warm when you’re idling. To fix this, you should replace the air filter with a new one. This will ensure that the air conditioner is getting enough air to cool the air inside the car.
If the issue persists even after replacing the air filter, then the problem may be with the compressor. The compressor is responsible for compressing the refrigerant and pushing it through the system. If the compressor is not working properly, then it won’t be able to push enough refrigerant through the system, thus making the air conditioner warm when you’re idling. To fix this, you should have the compressor checked and repaired if necessary.
Finally, the issue may be caused by a faulty thermostat. The thermostat is responsible for controlling the temperature of the air inside the car. If the thermostat is not working properly, then it won’t be able to control the temperature of the air, thus making the air conditioner warm when you’re idling. To fix this, you should have the thermostat checked and repaired if necessary.
These are the most common causes of why your auto air conditioning gets warm when you’re idling but then cold while you’re driving. If you’re having this issue, then you should check the air filter, compressor, and thermostat to see if any of them are faulty. If any of them are, then you should have them checked and repaired as soon as possible to ensure that your air conditioner is working properly.
