1998 Volvo S70 230k NO A/C at all

The lights on the A/C and the Recirc do not light when pressed.
I don't sense a change in the air when I press the recirc button either.
The clutch does not engage. Jumperinging the pressure switch
back by the firewall does nothing.

The fuse 25 A #31 labeled "A/C" is fine.

The clutch rotates with the hand. It is not really so easy to turn,
but a child could do it. I have recharged the AC with R134 and the
pressure displayed on guage looked high enough.

- the wires to the compressor look ok.

- last summer I reshimmed the AC per online advice, calling for three small pieces of Visa Card
installed on outside with crazy glue last summer. Card pieces are still in place.

In the main fuse/Relay box - the one with the huge link fuses -
there are three large and one small relay. The small one
is labeled "AC Comp" could this cause all the problems listed above?
If so how would I go about testing the thing with a DVM?

Do you think it is the controller in the dash that is bad? Broken solder?

Many thanks, Mark
