Usually leaks occur on the 100 in the rear AC system. There are cap kits for it to disable the rear and fix most leaks, allowing the front main system to still operate. In a lot of cases, most people haven’t even used the rear system.Yea, I'm not optimistic the system will be leak free. I haven't read about where the suspected leaks usually occur or what the key failures are in this vehicle and honestly I've never worked on A/C systems. We're headed on a short road trip Monday and my wife and I agreed we need A/C so hopefully it lasts long enough in this heat we're facing.
