A/C cutting on and off

[acw746]

Hello, I have a 2019 1500 classic tradesman 3.6 for the the last few weeks of my A/C cutting on and off while driving. I was wondering if anyone else has had these issues. I've checked and replaced fuses and relays and it hasn't helped the issue.

It possibly low on refrigerant or a sensor/control issue causing the cycling

Do you mean air stops coming out the vents? or just warm air on and off ? most likely low on refrigerant like mentioned above

You need to put a set of gauges on the system to see what is happening but does sound like is low on refrigerant.

Sounds like you are saying actually turning off and not just cycling a lot, correct? Either one can definitely be from low refrigerant.

Sounds like low on refrigerant, If the compressor is cycling off/on, for sure need gauges to check hi/low pressures.
