Took the 81 on it's first long trip over the weekend, about 275 miles. She drove good at highway speeds, but the AC seemed to be lacking to non-existent. So today, I first put a cut-off switch on the input water line to keep the hot water from the heater core so the AC won't have to work so hard. After that I was looking at things over seeing if there was anything else going on. All of of sudden....mind you it wasn't a very quick sudden...more like a Duh, I noticed something. You guys see the issue why the AC isn't working (2nd pic) ?

Well out get some parts and see where it goes from here.
