If your car’s air conditioner stops working on a hot day, then the ride to your destination can be quite uncomfortable. The air conditioner won't run properly unless your engine is running. Its just a compressor, it turns vapor into liquid. Turn the air conditioning on while the car is running. I get a lot of questions about car air conditioning systems not blowing cold enough. , this happened suddenly. A/C stop blowing.
