I have 2020 expedition limited
56k miles

I noticed the suv AC is nice at beginning then slowly dies on me. I also check for the leakage of Ac drain pipe next to the passenger seat area but the rugs are dry.

Is it low on Freon ?

Also the auto start/stop has stopped working.

Are these issue related ?

What can I do to fix my AC.

The cabin air filter seems to be not that dirty.

You should provide more detailed information.

Does the a/c slowly stop cooling, or does the airflow become reduced (or both)?

The system does not use Freon as a refrigerant.

There may be one or more stored trouble codes for the stop-start system.
