With it being a specialist option/spec I can't believe the wiring for the air con will have changed during the SPi/MPi incarnations. My '98 JDM (with A/C) is combination of SPi/MPi, basically an MPi with the older SPi throttle body setup.

There is also the possibility that the rotary temperature control has worn out over the years, so instead of telling the compressor to engage, it sends nothing. Or AC Thermostat failure is also very common.

I've been able to locate anew rotrary switch and thermostat.  I'll install them and see if that fixes things.

Where is the a/c thermostat located?

 

It will usually be located in the left-hand parcel shelf, above the aircon blower unit.

It's behind the dash pocket on the passenger side.

I really ought to change mine as well ... it'd be nice to have a little more control over the temperature rather than very cold to very very cold! I'm not sure that it's failed but I don't think there's any way to test it.

It is a Japanese import with the two wheel-dials for the ac.  I believe it is all original.  I cannot see, without dismantling, if there are any identifying marks on the compressor but anyway that seems to be working.  Evidently I have an issue with power to the compressor.  Do you think the wiring diagram from the 1997 diagram is correct for my system?

The fan switch on the 97 diagram is a 4 position unit. The 2 wheel switch Bobbins refers to is a variable resistor type. Try the 98 diagram
