I have a 2013 328i and have issues with the a/c. So far I've tested the a/c compressor and also the fuse that generates voltage to the a/c and both are good. The a/c still does not work what could be the issue?

Refrigerant?

Do you have a black light to shine on the A/C lines or compressor? Refrigerant typically has black light dye in it to help find leaks. If you have a leak and pressure falls below a certain PSI, most, if not all modern cars have a built in fail-safe that will prevent the compressor clutch from engaging so that the compressor won’t get damaged. The only other thing I can think of is maybe a bad relay? Have you checked for voltage at the connection to the compressor?

Yes I've checked the voltage and the compressor isn't getting enough power it needs

But have you checked voltage at the compressor? If you've checked at the compressor and get nothing, and the system isn't leaking, I would suspect the relay.

Any luck getting this resolved?
