Default air conditioning issue

Hey everyone,
I am a new owner of a 1996 moonstone pearl LS400, and I love it!!
I bought the car about a week ago, and everything seems to be great about it.
Only thing is, the ac does not work and summers in Las Vegas are no joke!
But, i need help.

I was told that the ac does not work due to the climate control panel having a short in it.
When pressing the ac button on the panel, it does not light up or respond. But when i press "auto" the ac button lights up and my vents blow air and the button responds to how strong i want the air to blow, but the air does not get cold. When the "auto" button is pressed, the ac button responds by the green light turning on or off when i press it, but the air never gets cold. When i select the off button, and then select the ac button , it goes back to being unresponsive.

I did a diagnostic by pressing the circulate and auto button, and the only codes that came up were
16, 21, (i was in shade) and 24, but i cant find the meanings of these codes.

Any help would be very appreciated. Do you guys think its just the climate control pane land the fact that the ac button doesnt work? I was told that button linked to the ac compressor to make the air cold, but i'm not familiar with these cars too much. The vents do blow air just not cold, thank you

Sounds like a relay or compressor clutch issue. Could also be a locked up compressor. Also could be the clutch control wire from the a/c headunit but that's less likely...

Not likely to be the climate panel?

In the grand scheme of things, for every climate panel that goes out in any brand, there are 10 or more compressors that fail...
