When does the AC blow warm air or cold air?
The AC on my 2008 2.0 L turbo now only works when I am driving at speeds of at least 30 MPH. When driving at slower speeds or idling, the AC blows warm air. I brought car to two VW dealerships to have their service department diagnose the problem.
Why does my air conditioner get cold while driving?
One of the most common causes of the symptom you’re describing is when you have a bad or failing AC high pressure hose. The high pressure hose is designed to increase and decrease AC pressure during different driving conditions, since the AC drive belt will increase in speed as the vehicle accelerates.
What should I do if my car AC keeps blowing warm air?
Remember not to be too harsh with the cleaning. That might damage the structure of it. If you’re done with both of the steps, take the coil out and clean it off with the best air blower for the car. If you don’t have any hot air blower, you may try it to keep under sunlight or dry air.
How does an air conditioner work in a car?
Your A/C works by compressing freon, cooling it down since it’s gotten hot from being compressed (through the heat exchanger in front of your car), sent to an expansion tube or valve which causes it to cool down (since decrease in pressure means a decrease in temperature) and into another heat exchanger in your car. This cycle repeats.

What to do if your air conditioner is blowing cold air on one side?
If the air conditioning in your car is blowing hot air on one side and cold air on the other, there could be a simple fix like adjusting the temperature or it could be time to replace a part like the temperature blend door actuator.
