with the compressor running.
the compressor is not running. Check your breakers.
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.
jump a hot wire downt to it with it running with gauges on it and read the readings.
Compressor not running? Check fuses, check switch
If the compressor has stopped running altogether the AC will not work.
Is compressor running? If refrigerant charge is low it will not
Check the ac compressor and clutch to see where the noise is coming from. Also check the compressor drive belt for wear.
When you turn on the AC, check to see if the compressor is running. If the compressor clutch is not engaging, it might be as simple as low refrigerant level. Automobile AC is not like a home AC. Since the compressor cannot be sealed, the seal always leaks a little and you need to occasionally add a little refrigerant.
There can be a couple of reasons due to which the AC compressor of your car might seize to work. First of all check the wires leading to compressor and the fuse switch. Next you have to check if the compressor holds enough gas for AC to work. Also, check for a leakage in steel pipes that circulate the air.
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.
A malfunctioning AC compressor could be caused by issues such as low refrigerant levels, electrical problems, or a worn-out compressor. To check if the AC compressor fuse is the cause of the issue, you can visually inspect the fuse for any signs of damage or use a multimeter to test for continuity.
