The Normal Temperature Range to the Fan Start is: A/C ON 181 F.
A/C OFF 199 F. When the Engine Reach this Temperature the Fan should start.
OK. Do this simple test.
1---- Start the engine, Desconnect the ECT Switch located on the Radiator,
See if the Fan come ON. If yes, if not go to step #2
Connect the ECT SWITCH and leave the car Running and with a Temperature gage.
See the temperature, if the Temperature go more than 199 F.
Turn the Engine OFF.
Disconnect the ECT sensor and check for Ground at the WHITE/BLACK wire.
If ground exist, Replace the ECT switch.
But if not. Check the wire for any damaged, and the ground at the Front Left Fender.
Repair as need.
2---- check the Fuse link RDI FAN . 30 amp.
Check the Fuse link CDS FAN 30 amp.
Replace if need.
And Return to step # 1.
Check the Radiator fan Relay, Rad fan relay 2 and 3. Replace if need.
Ok. I hope this help on your question.
I can give to you the WIRING DIAGRAM of the Fans, But I need a E-MAIL adress to do that.
Thank you for use fixya....

Chances are it is the resistor. I had the same problem with my 97. Then my blower motor blew. Take the resistor out, and check for burnt, or corroded connections. If found replace the resistor. They blow when the blower motor wears. It starts to draw too much power through it to operate it. And burns out the connections. So I would advise replacing the motor as well.

As an aside: the recharge kit can be had with a pressure gauge for a few dollars more and comes with adequate instructions on what the appropriate pressures are. Works like a charm even for casual 'experts' like me (and you.)
