Question about Cars & Trucks
Nisan Micra ( 2005 ) - radiator fan not working when cooling needed. Fuses and relay are fine, he grounded the fan ( I think that's what he did) and the fan worked. He concluded the Sender' was faulty but there were 4 of them. Can you tell me which is the relevant one, please ?
You must test all. However it more easy if you RUN the scanner/computer for easy diagnostic and fix it.
You must look, for dirty, corrosion,oxide, loose wires or connector.
Test the voltage in fuse, relais, sender.and the Fan for voltage with VOM .
God bless you

Check for a switch at lower part of rad. Should see a wire harness & plug on a sensor at bottom of rad. This sensor/switch also operates fan on/off according to coolant temperature. You may need to disconnect battery to get at it safely.

remove the cooling fan relay you should have power on the pink and black wire and the solid red wire going to the base for the relay if you do then check then turn the a/c on and check for your ground sigal from the darkgreen and white wire if no ground you have a bad fan control module located on the right side of the engine compartment

no the flush will not help. Will the fans come on when you turn the ac on.. You should have a fan relay under the hood.. Have you hooked up a scanner to the computer.. If it never gets hot enough it wont turn on. The fan is computer controlled by a modulated ground. If you dont get a ground signal at the motor when at 230 degrees you may have a defective PCM.

You have 2 engine coolant sensors one on front of engine, near thermostat housing and the other on the right side of the engine above the starter motor. You probably need to change the other one.
