Any one know anything about A/C?
The interesting thing about this system? NO sensors at all! All it has
is a temperature sensor on the evap for the thermostat. That's it. The
other wires are 3 for fan speed, one to turn the system on, and the
power and ground!
The A/C was just serviced in 2001 I think - with R12. So I didn't
bother with o-rings.

I didn't replace the drier or any O-rings and assumed I would have leaks. Two years later it blows cold. It's probably a shade less effective than R-12, if I had to guess, but not bad.

It is one of the two switches in the A/C line at the passenger end of the A/C condensor (the thing in front of the radiator :O). Your's may be located elsewhere b/c of the dealer install. If your 12v to the wire on the compressor works out, then bypass that pressure switch (jump it), and see if you can turn the compressor on from inside the car.
