The air conditioner is pumping hot air.

Hello, I'm having AC issues and can't seem to locate a solution.
My air conditioner stopped blowing cold air, and I ran an OBD scan and received the diagnosis 9C6A (compressor clutch). Now, when I push the snowflake clutch, neither the compressor nor the fan turn on.
I tested a few fuses, and everything is in working order.
Any recommendations on where to look first for the issue?

The level of refrigerant is first checked.

It was crowded to capacity days ago.

It was the same for me.

It worked for a day after I refilled it, but then it stopped because the gas was leaking out.

Don't care enough to look for the leak. Low pressure was the problem, not the clutch.

After you refilled it, did it work at all?

Verify compressor wiring for continuity.

It's possible that the problem lies in the compressor...

It stopped cooling, so I left the car to fill up the freon because the car is old and I thought it was empty, but it was only half full. Even after the mechanic filled it up, the bus didn't work.
We've checked to make sure that the compressor clutch is dead and doesn't work when I press the snowflake button. So we have to get a new one and hope it works.

When the air conditioner is turned on, do you receive electricity to the compressor?

My acquaintance was verifying that, so I'm not entirely certain. He stated that the resistance in/from (uncertain) compressor was perhaps 5,000 ohm, if that says anything.
