So my ac never worked since I got the car I dint know what what the issue but there was no refrigerant. As I thought there is a fail safe system to prevent compressor from engaging when there's no pressure so my mechanic filled it with nitrogen and we barely lost any pressure(as my mechanic discovered the low side valve wasn't tightened and was leaking. so we vacuumed the system for like 38 minutes, filled it with stop leak and a can of refrigerant my mechanic said the compressor made some smoke and noises on initial start up but pulled through and was able to free itself. Now the Ac runs mint loving it.
