Fans can still spin but be bad and use too much current,
any motor made can do that, even the fuel pump too.
working with no shop manual are you? buy one , it is worth every penny ,first time is saves you $100 parts or labor, bingo free book./

Hi.....
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....
Did you replace the sensor by the thermostat in the engine block or the one under the drivers headlight, There are two, the one next to the thermostat controls the temp gauge in the vehicle. the one under the headlight assembly controls the actual fans and is a electronic module. You have to remove the head light assembly to get to it.

Hi,
Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.
Cheers,
Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."

1997 Plymouth Neon, have replaced radiator, radiation cap, thermostate and hoses, still run hot. Fans do not seem to come on, where is the temperature sensor on this vehicle?
