    My 91 Accord's A/C is blowing warm air. I first figured that I needed a
    freon refill, so I wanted to give that a try. When I tried to empty out
    the old refrigerant, I couldn't get good vacuum pressure on the line.
    Obviously, I suspect a leak in the line. Is there an effective way to
    pinpoint the location of the leak, and is there a particularly
    effective way to seal the leak? Or am I overlooking something else that
    I can't think of?

    If you can't get close to a reasonable vac then the leak is quite big (but
    check it's not leaking at the connector). Try pumping a little bit of air in
    (not too much as you don't want to introduce moisture). You should hear it
    leaking out somewhere. I've seen quite a lot of Hondas high pressure pipes
    fail under the pipe clamps (traps moisture, etc), 2nd favourite is the
    condensor

    Soap bubble test, flourescent dye, electronic leak detector all come to
    mind. The local Autozone has a rack full of AC tools and supplies,
    including leak detectors. If you want to try the shotgun approach, buy an
    O-ring kit and replace all the O-rings in your system. One doesn't normally
    "seal" AC leaks, but rather replaces the defective part. A vacuum pump is
    not a good way to evacuate a system which might have refrigerant in it. If
    you manage to suck liquid, you could damage your pump. Nowadays "they"
    recommend a recovery station.
