I'll have the fan on the second notch, in the morning on cold, it works. But as the day gets warmer it'll start blowing warm air. As the day starts cooling down it'll start working again. If I try putting the fan on high it'll also start blowing hot air.

Hi,

This could be the result of a few things. It could be the system is low on refrigerant or even an issue with the blend air door.

When the system starts to blow warm air, pay attention to if you hear the A/C compressor cycling on and off. You will likely hear a click when it turns on or off.

Also, take a look through this link and let me know if it helps you:

Let me know.

Take care,
