Why does my AC stop blowing cold air when I accelerate?

RE: a/c stops blowing cold air when accelerating
You need to verify if the compressor clutch is cycling off or if the vents are closing off. If the compressor is constantly kicking in and out, every few seconds, then youre low on freon. If the vents are just closing, then you have a vacuum leak somewhere in the system.

Just so, why does my AC only get cold when I accelerating?

The cooling fan in the condenser is the first thing that you should look into while finding out the reason for car air conditioner not blowing cold air when idling. If the fan is damaged or cannot run with its full force, it cannot cool down the heat coming from the Freon (refrigerant) through the condenser.

Furthermore, why does AC only work when car is moving? When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation. Other possibilities are that the compressor clutch is not cycling as intended or that the condenser might be blocked or dirty.

In this manner, why does my AC stop blowing cold air when I stop?

The most common cause of window air conditioners not blowing cold air is a lack of adequate air flow. If the air filter is dirty or clogged, there may be little or no air flow over the evaporator coils, which may cause them to become too cold and frost or ice can form on them, restricting the air flow even more.

Why is my car AC blowing hot and cold air?

Car AC blows cold then warm. If your car AC blows cold then warm, the cause can be a low system charge, moisture in the system, a malfunctioning expansion valve, clogged evaporator fins or an overcharge condition. Here's how to nail down the cause.
