Ac compressor

Might just be a compromised o ring, let a shop test for leaks, then recharge afterwards. Those $30 DIY recharge kits can be a total waste of money if your system has a leak.
FYI when you are low on refrigerant (due to a leak) your compressor can cycle on and off continuously when AC is on. People tend to think it's a bad compressor, but it's not, it's just low on refrigerant.
