It might be the sending unit. On my 95 SC there are 2, one for the gauge & the other sends the signal to the PCM, then to the IRCM (behind the passenger side headlight) to operate the fan. Not sure if it's the same on 96-97's with the 4.6, but it should be.
Also, if the fan is a 2-speed you might only have one speed that is functioning. Borrow a scanner from someone & do the KOEO (Key On, Engine Off) test. I'm pretty sure that tests both speeds of a 2-speed fan motor.
