Why does my car AC only work when I drive fast?
A defective AC condenser fan is a possible reason why your AC only works when driving. When your car is in motion at top speeds, the condenser does not require the fan to cool the freon. The condenser’s cooling fan is responsible for cooling the freon’s heat when the vehicle is in a stationary position.
What controls the speed of the AC in a car?
The fan circuit has a resistor which controls the speed of the fan blowing air through your vents. When they go bad, you only have one speed, full blast. Usually an affordable fix, the hardest part is finding the location of the resistor under the dash.
How can I increase my AC speed?

What should temperature be for car AC to blow cold air?
Once the refrigerant is filled, head inside the car and with the thermometer placed inside one of the AC vents, note the temperature. An ideal AC should blow cold air which is about 28 degrees.
