2006 ac compressor won't come on to accept charge

Help
2006 Prius 104,000 miles-
9 months ago the AC started blowing "not cold" air
I put a can of suitable 134a WITH the correct oil in-and it blew cold for about 6 weeks
then the weather became a bit cooler-and my son drives it-
so I ignored it as it cooled less well
Yesterday I tried to recharge it again-no go-the AC literally seemed to be blowing HOT air
the compressor wouldn't come on
Guessing so much 134a is gone that it won't come on-just like a regular AC
How can I trick the compressor to come on so it can accept the charge
Yes I'm aware the orange covered cables are 200+ volts-and could kill me-
No I don't want to die-so I'll follow any instructions that involve electrical connections-carefully
Frankly I might just chicken out
Oh-I can't -couldn't find any compressor fuse??
I found a A/C fuse under the dash-but it was just 10-15 amps-12 V amps probably-so no way is it the compressor-110 watts-?? Must take 1000 or more watts to drive that compressor
Thanks
Charlie

Thanks for the reply.
I should have been more clear.
If I can't fix it-I'm not going to bring it to a shop-$1000-$1500 to have it "maybe fixed"
In NOLA- most of the shops I have dealt with-including dealers- are dishonest and not competent.
They "might fix it" but they might not
and on leaks-10 yo A/C in NOLA run 9 months a year-it is on its last legs anyway
so "breaking it worse" isn't much of a concern.
But mostly I can't won't pay $1300 plus to get an A/C "maybe repaired"
Now the last dealer we went to-about 3-4 years ago-traction battery "died' just 44 days INSIDE warranty-they did a good job-
but the service writer started things out by telling me "it probably wasn't the battery-and it probably was something "out of warranty"\
despite my telling him the code-forget what it was-and having the screen giving the "I'm dying get to dealer" warning
anyway they did a good job-no charge
but i general ALL dealers-the service writers- attempt to screw you -with dire safety warnings -and out right lies
so I NEVER will use a dealer except for jobs that can't be done anywhere else
and in general-won't bring it to a shop
In any case-If I can't fix the AC-or figure it is too dangerous too complicated requires specialized tools that are too expensive-or too likely to "break the car" it just won't get fixed-
haven't paid a shop for any work in maybe 20 years-
the Prius AC might just have to remain "broken" until I get around to it

Thanks-just what I needed.
Good instructions I can print out-and keep at hand so
1)no dead me
2) no dead car
3) with luck an ac that will cool


Oh-I must have been unclear.
There is certainly a leak
when I charged it 9-10 months ago-I charged it-full can(10 ounces -9.5 ounces of 134a + .5 ounces of high diaelectric lube all came in one can-for hybrid vehicles)
it immediately went from "not cool" to cold-as it was being charged-literally minutes-just like a "normal car ac with a low charge)
it was fine for 3-4 weeks-then slowly became less and less cool-but my son drives it-and it was winter-so I ignored it
when I went to recharge it-it wouldn't accept a charge-compressor obviously wasn't on.

I will see if I can rehab my scan gauge-it has been on and off working lately 11 years old,so.. good excuse to get another to get codes-and read mpg on the other vehicle
Thanks-just what I needed

ps in NOLA an ac that lasts 10 years-is the exception 100,000 miles is 5000 hours-4000 with AC on-car a/c take a beating-so 4000 hours service-seals o-ring have taken a real beating-bumpy streets lotta service twisting bumping of every joint-
it held a charge for several weeks-so maybe it isn't an actual hole in a "hard part"
