Honda accord ac problem

ok so my freon level is perfect but my clutch
doesn't engage at all,  but if I jump the relay
in the relay panel under the hood, the air
condition clutch engages and it blows ice
cold air no problem.  But when I put the relay
back in it goes right back to not working.  Is
their another realy for the clutch
specifically?   I dont understand when I jump
the relay everything works fine,  am I
missing something here,  some one said to
trace the wires coming off the ac
compressor clutch and I will find a relay
thats not in the relay box.  Does anyone
know where this is located or if its even
true?
