Well technically you are supposed to recover any remaining refrigerant before disconnecting any hoses.

Sure, it can get complicated. But in my experience many problems come down to leaks. If you can get good at finding and repairing leaks, and then properly recharging, its a good foundation for fixing many issues.

Do yourself a favor and invest $200 in a vacuum pump and set of AC gauges. Watch 20 minutes of youtube and you will have the tools and skills to troubleshoot this issue and anytime you have AC trouble with other vehicles in the future. Honestly its not that complicated.

I opted to install the manual "cable type" valve from an m998 that I can control it from the cab manually. In a pinch, you can use a 1/2 pex ball valve.

FYI, my front unit wasnt blowing cold air. Turned out the AC was fine, but the valve for the heater core was stuck in the open position so it was running heat and AC at the same time. Easy fix. And yes, anyone with standard equipment should be able to diagnose and recharge the AC.
