First off sorry for the long thread.

Hi, i have a 2000 Dodge Dakota Quad Cab 4x4 4.7 Lt V8. I bought it
used, and just got around to getting the A/C recharged because it
wasn't blowing cold air. I took it to my highschool because they offer
a free A/C recharge ( pay for freeon thats all). Well they gave it back
to me at the end of the day saying that they recharged it, and to the
best of their knowledge it had no leak. They tested the temp. on it and
it read 40.8 Degrees F. The next day i turned the A/C on and got warm
air. I checked under the hood and the A/C compressor clutch wasn't
engaging so I took it back to the highschool shop to see whats up with
it. he told me that the compressor wasn't engagin, and that it would
have to be looked at tommorow. So me being the dumb A## that i am
attempted a test i found on the internet, you guys know as jumping the
clutch to test if it was working. I hooked up a positive and negative
wire from the battery to the positive and negative hookup on the
compressor ( was this bad to do??). The compressor didn't engage, so i
figured i'd stop before i wrecked anything. The next day at the shop
the teacher discovered their was a leak that had drained almost all the
freon in the system within 24 hours. The leak was located up by the
radiator area ( they used an electric freeon detector and they belive
it's coming from up there). So that takes care of my leak problem, i
know that there is a leak up front, and that is probably why the Clutch
won't engage. But the Clutch is blowing a fuse when ever it is plugged
in now and turned on , this statred from the best of my knowledge when
i tried jumping the clutch. It's a 20 amp fuse shared by the horn only.

Did i fry my clutch by jumping the wires? or is it just because there
is no freon left in the system? Also is there anyway that i can
possibly fix this leak on my own, the shop quotes to have it fixed are
rediculous.

Thank you all so much for the help,
