You just can't make new products with R134. Beyond that there's nothing for at least the next 4 years. And R1234yf systems are about 95% compatible with R134... Just don't blend the two.Also: retrofitting is illegal. The EPA considers it tampering in violation of the Clean Air Act and the fines are huge.
You can make new products with R-134a. There is no ban on it, but manufacturers get credits for using refrigerants that have low global warming potential.You just can't make new products with R134.

You're probably thinking of the old school refrigerants. Yeah using those is a big no no. A blend of propane will work but there's a very explosive reason on why it's banned from automotive.
I have limited experience with a 2019 gasoline Cruze as a loaner car for a warranty repair, and that wasn't during a hot day.The Cruzes problem is that the condenser heat soaks at idle, because of the jet hot mf'in turbine 6" behind it. LOL. The fan is too small and the engine bay too tight to evacuate heat when stopped. That's when AC can't keep up, while in motion that sh!t is ICE cold.
I'm going to have them put it on the lift and look for dye in the evaporator drainage tube because that's the easiest way to do that without tearing into the dash to check. If there are no leaks anywhere else easily accessible and the system is low on refrigerant, I would assume the leak is in the evaporator.Getting a diagnostic scan , and taking a leak tester to test for leaks from evaporator would be wise. Freezing kills them. There's an issue with this in certain Impalas due to their drainage and AC software.
Oh, this is something I've never heard of! What tool? I need to know this ASAP so I can tell them what to do to get the best possible outcome.The GM specified service tool for inspecting for leaks is very accurate, and quickly finds leaks. If you can get them to fire it up and check the drain or a vent that would be best.
