The auxiliary fan should turn on at 238* and is controlled by temp. alone. As stated above some of the '85s only had one main fan...it's possible you haven't noticed the aux. fan running simply because the temp. switch hasen't seen 238*'
The way to test the circuit would be to remove the wire connector from the temp switch on the pass. side head (between cylinders #6 and #8) and ground that wire (dark green)....if the wiring/relay and fan are good, the fan should run. There is a fusible link which feeds the relay which is "hot" all the time.
BTW--- the ign.switch needs to be on for the above test.
