William, know there is a so-called 'final filter' in the side arm of most Pantera OEM expansion valves, under the dash between the glove box & console. It is a tiny conical brass screen that catches pieces of dryer can media, flakes of rubber off hoses etc, etc. Mine was plugged solid so practically no flow. Replacement e-valves don't have the screen, apparently to increase flow & thus cooling. To remove, fish it out with a hooked scribe and soak in solvent to clean. It just sits in the valve. But 50 yrs is a loooong time to 'sit' if no one has ever cleaned it.

Oh, and replace the dryer can; I cut an old one apart and what was left in there you wouldn't want to flush down a toilet! Originally 1/3 full of small moisture drying pellets.
