Had bad clutch on ac compressor. Replaced compressor with clutch, drier and filter. Pulled vacuum on system. Checked ok, no apparent leaks. New high pressure switch installed. Tuned on a/c switched to high, blows fuse. Unplugged high pressure switch connector fan stays on, no problem. Turn off a/c, plug in high pressure switch and unplug low pressure connector, turn on a/c /fan stays on does not blow fuse. Turn off a/c plug in low pressure connector blows fuse. Jumper low pressure connector/turn on ac blows fuse. Has one can of freon charge

You didn't really identify which vehicle this is so I'm taking a guess on this. Is this auto temp control and what vehicle is it? If it's auto tem p then the diagram I'm sending isn't any good. But heck to make sure diode at clutch is good then check relay and fusible link. It may be the relay pointed out in pic as well. If this iauto temp where you set the temp then disregard everything here and give me the correct info.
