Help!
It's May in Tucson, and my AC is on the fritz.

My 92 Accord Wagon has an apparent AC leak. AC worked in Feb, when I
bought the car, and when I exercised it (but didn't really need it)
during the winter and spring. Now that it's 100f, there is no coolant
pressure at the filling valve and, unsurprisingly, no cool air. I've
got a leak and am looking for a schematic or service manual for the AC
system. My Clymer is worthless. Do any of the aftermarket manuals
cover the AC system in any depth? If not, where can I find the info?
Google isn't sniffing out what I need.

I've fed the system a small can of 134 based coolant and oil, with UV
dye. This gets me slightly cool air, but does not reveal any leakage.
I haven't run the system for more than a few minutes for fear the
mongrell coolant load will damage something.

The previous owner had just installed a new compressor before selling.
There is no sign of dye on or near the compressor, or fittings.

I'd like a fairly comprehensive AC guide, so I can take out various
sections for cleaning/testing/replacement.

Thanks!
