1990 Corolla GTS 4AGE FWD

 

 

I have had this car for about 5 years now, my cousin had it before. As long as both of us could remember the electric cooling fan runs soon as the ignition is turned 'on' or when the car is running...then the fan runs constantly never shutting off. I have replaced the fan relay switch(fuse) and the temp switch (or ETC I think its called?). Hasnt fixed the problem. I have two different repair manuals both have really no info on the problem of running continually (Chilton and Haynes manuals). I have been pulling apart my wire harnesses trying to find any loose connections or what have you, no luck so far. If anyone has any suggestions it would be terrific.

 

Also posted some questions about harmonic balancer w/ pics.

Tried another cooling fan relay, Current one may be stuffed? You said you have already replaced the sender..

 

 

 

Yep, temp sender was replaced. I checked the connecter with my volt meter to make sure the wires were good. Also checked the fan relay fuse to, making sure the brand new one wasnt shot. Someone mentioned using jumper wire to GROUND the fan switch wire, which lives on the thermostat housing on the lower rad hose. So I will try that next.
