It's likely that it may need a refill as they do slightly 'leak' over a number years, and it depends on when it was last refilled/serviced. If you are very lucky you might spot a loose connection to the compressor, or the fuse, or an electrical break somewhere else in the system.

If that doesn't cure it, you could have the fault codes checked, or take it to an aircon specialist, or take it to a fiat dealer, but be prepared to spend as much if not more money than the car is worth.

It could need a refill due to a leak somewhere. If not check codes for A/C relay. Could be going bad.
That relay is located under the right headlamp at the very botton attached to an A/C pipe.

P0530 stands for a/c pressure switch. It pops due to the reasons I explained above.
About the KMs flashing you would need MultiEcuScan and scan the body control module and check for errors.
