What controls the stock s14 e-fan? Can't get it to turn on

[redsx13]

Hey guys, so it's been a while but I have decided to consult some fellow nico members with a problem I've been having. So ever since I bought my 97 s14, the stock e-fan has never worked, now this wouldn't be too much a problem exept for the fact that my car doesn't have a clutch fan installed.

Now before you say anything, I would like to point out that I am not going to rely solely upon the stock e-fan to cool the motor but I would like to use the 12 volt output from the stock e-fan plug to operate a relay which will control a set of aftermarket flexolite fans. Basically, I don't want to spend money on an aftermarket fan controller if my car already has one built in.

So my question is, what controlls the stock e-fan and what would cause it not to work? (other than fuse/relay in the engine bay)

Just for some added info, when I bought the car, the person before me had pulled out the fan relay and had plugged two wires in the relay socket which lead to a switch in the cabin. This essentially bypassed the relay so when you turned the switch on the fan comes on. I just can't get the relay to turn on automatically.

Thanks in advance for your help guys

The fan your talking about is controlled by the ac system. The 240's are ran by the clutch fanfor cooling the motor. However, I have my cooling system setup with the s13 coolant temp switch (mounted to a pipe on the lower radiator hose,and relocated to top hose)that activates a 30 amp relay for the fans. I believe the ecu controls the ac fan on the s14's.

actually the Electric fan is a two step, one is for ac the other is for when the car gets too hot. Alot of the autocross guys use the factory setup cause the Ele keeps cool along with the clutch fan when revving high
