Ok, this 65 Wildcat Convertible of mine has factory AC, everything kicks in as it should, suction pipe gets cold, even frosty, high side port is right on pipe close to compresser, gauges both stay close to the same pressure all the time. Normally that would be an expansion valve problem but this setup is different, uses a suction throttling valve ahead of the expansion valve and I don't believe it is available anymore. Does anyone have any experience with this? It seems all the baffles are working fine, move the lever to heat and it changes immediately and back again.
