I have a motorhome on a Ford E-350 chassis, with a 460 engine. It has not been used for more than a year, and when I turn on the AC, the clutch cyles on and off. I suspect I've lost refrigerant, and have purchased a recharge kit. The high pressure port is right by the rad., but I've followed the LP line as best I can (it's a very cluttered engine space) and I can't find the low pressure chsrging port. Any ideas?

Try and find the accumulator a can thing 10" tall x 4" around. Maybe black or silver port should be there. But no telling what AC system was installed. Check at compressor sometime that's where it is.
