Why is my 2003 Tacoma a/c sometimes not working and blowing hot air?

What is your question?

Intermittent blowing hot air when I turn on the ac. I have had it tested for leaks and professionally recharged. Sometimes it works great, like this morning, but couldn't get it to work yesterday afternoon; even changing it to heat, turning truck off and restarting etc.. it appears to be be getting more and more frequent. Only noise heard was what sounded like something moving around in ac vents? Best way I can describe it but that only happened one time last weekend. It was in the dash. The air conditioning was working great when it made the noise, but also worked great today with no noise. Hope this helps describe my truck's issue for help!

What makes this problem better or worse?

Appears to be worse when it's very hot

How long has your 2003 Toyota Tacoma had this problem?

Couple months but progressively worse
