Thanks all for the pillar info. It turns out that the relays and fuses that
are specific to A/C are hiding right above the steering column and just
hanging there. This matches the somewhat well-hidden electrical diagram in
the Bentley (97.138) for the 1984/1985 version but does not match section 87
which shows the service procedures for A/C. The A/C stuff does not appear in
the main electrical diagrams. It is interesting that the radiator cooling
fan can be affected by the refrigerant pressure and thus has extra wiring
that does not show up in the main diagram.
