Connect the No. 1 and No. 2 terminals of the compressor clutch relay 4P socket with a jumper wire.
COMPRESSOR CLUTCH RELAY 4P SOCKET
Does the compressor clutch click ?
YES - Go to step 6.
NO - Go to step 14.
Disconnect the jumper wire.
Turn the ignition switch ON (II).
Measure the voltage between the No. 3 terminal of the compressor clutch relay 4P socket and body ground.
COMPRESSOR CLUTCH RELAY 4P SOCKET
Is there battery voltage?
YES - Go to step 9.
NO - Repair open in the wire between the No. 14 fuse in the under-dash fuse/relay box and the compressor clutch relay.
thanks" IT wasn't me" for answering..
"This is what i did...and the compressor did click..did not engage at all...this test is done with car engine off"

tanks....
I just following the manual,it show that to test the compressor the terminal 1 and 2 jump is with car off .
however i think your point make sense.i am going to jump terminal 1 an 2 and see what may be.

So if you test terminals 1 and 2 and the clutch does NOT click or engage with the car on what would the fuse box be the problem?

Pfft! You have a manual, and you can't figure this out?!
You should be able to sort this out on your own. Follow the procedures, rule out the possibilities, find the culprit, fix it.
