Greatly appreciate your help.

Few Qs:

Where might I find shematics? Someone mentioned the Mitchell series at a
library. Mebbe the service dept would photocopy sumpn for me? Anywhere
else?

Besides buying the info, are those two free resources not enough?
You can even get the exact factory info back to 1990 at www.techinfo.toyota..com
for $10 per day. Print off what you need in .pdf form but it helps to
have Acrobat Reader 8.x.

Is the compressor below the alternator? Are any wires going to the
compressor necessarily for the clutch?

Yes. THE wire is for the clutch. No other "compressor" wires on
Corolla-esque cars.

How do I tell high pressure side from low pressure?

Only for the purpose of identifying where the switches are, the high
pressure line is smaller diameter. NOW, if you know that little about
A/C, please don't even think about servicing any refrigerant holding
parts (don't unbolt/unscrew anything at the compressor, condenser,
drier, evaporator, at any lines or on any lines). Don't touch it.
Don't even look at it. Just enjoy the sustain.

And this low pressure switch: It would be by the firewall? With two wires?

As previously stated, it is called a dual pressure switch and yes and
yes.

There is one set of fuses by the drivers' left leg. Is that the only set on
the drivers side?

Probably.

I'll check under the glove box again, but I did look, and nothing was clear,
like the cover on the driver's side.

BEHIND THE RIGHT SIDE KICK PANEL.

The MG thing is under the hood, clearly labeled on a fuse block. What does
MG stand for? Is that what they mean by heater/A/C circuit breaker, or is
this elsewhere?

MG is Toyota's term for A/C clutch relay.

I'm assuming that if something just goes out after a fender bender, it's
electrical. Reasonable?

As reasonable as assuming that a component was jarred hard enough to
crack and lose all refrigerant.

That's as far as I go without an exact make, model, year, and engine.
I can help -given that info- during normal work hours.
