Followup on '88 90 5cyl Radiator Fan Problem

["DALE BAXTER, DIR ENROLLMENT MANAGEMENT AND RESEARCH"<BAXTER@PPCC.CCCOES.EDU>]

To reiterate, problem was radiator fan runs whenever the ignition key is on.
Even runs when the thermal switch at the bottom of the radiator is unplugged.
Fan goes off but cycles improperly when 1st speed relay is removed.  Switching
relays doesn't help.
Have now tried unplugging the hi-pressure switch (unplugged both the green
and red switches located on the ac line under the shroud in front of the
radiator).  Fan still runs.  Did I get the right switch???
Also tried unplugging the thermal switch at the connection of the radiator
hose to the block.  Fan still runs.
This fan seems to have a mind of its own.  Any other suggestions???

Thanks,
Dale Baxter
