My A/C is extremely cold when I first start the car. However, when I drive it for a long period of time, and the outside temperature is hot, the A/C becomes less cold. When I hit auto (fan speed), with the temperature at 60 degrees, the fan speed bar goes all the way up to the maximum speed. When I raise the temperature to 75 degrees, the fan speed drops down to mid speed. If I drop the temperature to 60 degrees, the fan speed rises to the max again, but the air that comes out is not cold at all.

If the outside temperature drops, and I start the car again at night, the A/C becomes cold again.

I'd like to know if the problem is caused by the Relay, temperature sensor, or the temperature switch. If anything else comes to mind, feel free to bring it up. Thanks in advance.
