Guess I'd try swapping out the low and high speed relays (same relay as starter)...all found in the small square box in front of the large fuse/relay box. Along the way I'd look for signs of re-wiring in case a previous owner lived in a hot climate and wanted fans on all or the time. If A/C is on, fans will be on as well.

If A/C or Defrost is on, fans will be on...
