Could be significant. On the 87 and later vans the AC system is fed off an
independent wire directly off the alternator. This also powers the radiator
fan in a low speed when the compressor is called for. There is also pressure
switch control that operates a relay in the fuse box to provide an
intermediate fan speed when the AC needs it. If that wire was left off
during the conversion along with other issues the radiator fan can be
effected.
The supper high speed fan operation is fed from a 70 amp relay mounted above
the fuse box. It has a fusible link on it. It has its own feed wire from the
battery. One of the two red with white stripe wires. That wire can fail at
the connections on both ends.

What does a Subaru conversion have to do with the AC not being hooked up ?
