If the AC compressor is hot but not running, it could indicate that the compressor is experiencing a mechanical failure, such as a seized bearing or internal damage, preventing it from starting. Another possibility is that the compressor is overheated due to low refrigerant levels, which can cause it to shut down as a protective measure. Additionally, issues with the electrical components, such as a faulty relay or capacitor, may also prevent the compressor from operating while it remains hot.
Is compressor running? If refrigerant charge is low it will not
with the compressor running.
Idle the car with the AC running. Open the hood and look at the AC compressor- is the compressor engaged? (the front of the compressor (inside the belt) should be spinning. If not, then have the AC system recharged. If it is turning, then you've got the door to a duct stuck inside the unit.
jump a hot wire downt to it with it running with gauges on it and read the readings.
It could, the computer will disengage the ac compressor if the engine temp is too high.
If the compressor has stopped running altogether the AC will not work.
A capacitor in an AC compressor system helps to store and release electrical energy to help start the compressor motor and keep it running smoothly.

compressor not running or not not compressing
Look to see if the compressor is running when the ac is on. If not, then check the Freon pressure, as the compressor won't run if the Freon is low.
