Default weird a/c problem

anyone have a problem with their a/c doing this?

it only does it when the car has been running for a while or when its hot. the a/c runs fine when the outside temp becomes cool so im thinking it must be some kind of heat sensor

My car does the same thing also when the weather gets hot. Seems to me that are clutch on the compressor is toast. If you find a way to fix it. Please reply back.

Yes the problem is when it gets hot outside or when the motor is ran for awhile creating heat under the hood, the pressures in the a/c lines is lowered. Take your car to the shop or buy one of those recharge kits you can purchase at an auto parts store and recharge your a/c. You will not need a whole lot because your system is turning on and off. There is a pressure switch in the system and when the pressure gets low enough the clutch will shut off. When there is excess heat the air and refrigerant in the system becomes thinner, thereby decreasing pressure.

I have the same issue.. can you let me know if the re-charging worked for you? Also one thing to note from my car is that the compressor will only do that at idle. If I'm on the freeway it blows really cold and its only when I come to a stop that it starts blowing warm air..

You can't just charge the system and hope that it works. If the freon is low OR overfilled, it can cause the compressor not to work

You need to see if the compressor is kicking on and off, check the pressures and check for leaks before just putting in freon.

Also, you say it happens when it is hot outside or the engine is hot....do you have it on recurculate? Does it stop blowing cold (and the amount of air diminishes), and then after turning it off for a while it is fine? Could be the thermistor, or temp sensor on the evaporator. (this was an issue with some of the earlier WRXs)

Just putting freon in will probably not solve the problem. If you are not familiar with AC, have it checked by someone who knows.
