My AC recently started blowing warm air m, so I bought the ac recharge kit from AutoZone. However, the hose will not connect to the low side ac port. I've tried with the car on and off and have tried two different hoses but cannot get the hose to attach to the port. Anyone else experience this or have a solution?? Thanks!

Would be surprised if a 2018 already needs a charge.
Still under warranty? If yes let dealer handle it.
IMO if you are not experienced in a/c system diagnosis & repair, find someone that is!

Thanks for the reply, unfortunately I bought the vehicle used almost a year ago so there's no warranty. I brought to my dad whose been a mechanic for a long time and he checked it out and said the belt and compressor were both running so it looks like low freon. I just found out due to it being a "newer" vechicle, they've stopped using the R134A freon and have gone to the 1234 YF.

Manufacturer warranty still applies to vehicles that have changed ownership.

Whether or not A/C charge is covered is another matter though.

I highly doubt a 2018 vehicle has a refrigerant leak. The problem is most likely elsewhere. Make sure the heater blend door is working by confirming the air gets hotter when the climate control temp is set higher. Make sure the radiator fan is running while the A/C is turned on. If not, that's the problem. A tell tale sign of this would be if the A/C only blows cold air when driving at highway speeds.
