A/C questions

Low side port is under the low pressure switch, you
remove the switch and attach your hose.
I believe the AC compressor relay is under the dash on
the driver side, probably at fault for no comp with
switch jumper-ed. It is single relay socket size but
it is taller than most others.
Good Luck
