Couple things I can think of off the top of my head.. if it does provide cooling when the vehicle is moving, your refrigerant level is probably the issue - perhaps too much of it or too much PAG oil. This causes a low superheat and makes it more difficult for the heat exchange to occur. Bent fins on the condenser which are prohibitive to the passage of air through the fins is another possibility. When you get your car washed, do you put high pressure water directly to the grille? If so, there's a good chance its caused bent fins on your condenser (as well as on the radiator).
The main cause I see is an inoperative radiator/condenser fan.

It doesn't matter if the car is moving or not. If the alternator is working properly it should charge. For best results be sure everything is turned off inside the car..i.e. radio, air conditioning, ect....
Yes, it is possible to suffocate in a car if the windows are closed and the air conditioning is not working, as the lack of fresh air circulation can lead to a buildup of carbon dioxide and a decrease in oxygen levels inside the car. This can result in suffocation or asphyxiation.
It is not a good idea to try and fix the air conditioning in your car yourself. Try going to a mechanic or car repair shop to have your car air conditioning properly fixed.
The electric auxiliary cooling fan may not be working.
The air comes from the air outside and the air conditioning system in the car turns this into cold or warm air.
The 1939 Packard was the first car with a true air-conditioning system.
The motor is working harder to push more cold air in the vehicle.
Because the car is FIFTEEN YEARS OLD!! Nothing lasts forever--not even a Town Car.
Depending on the year, make and model many vehicles will have a very simple small bulb that blows out and in many cases you can just replace the bulb...........
For most cars the air conditioning is powered by a belt from the engine and even if the car is only idling it will be running without any meaningful effect on the car's battery. For some hybrid drive cars the air conditioning is powered electrically, so that it can work even with the engine off. These will drain the car's battery some, but the air conditioning controller will automatically turn off the air conditioning before this becomes a problem then turn it back on as soon as the engine is automatically restarted when it is again needed to drive the car.
Automotive air conditioning is the ac unit in your car. It's what "conditions" the air in your car, ie keeping the temperature inside the car cool or warm.
