Car overheating - fan not turning on. 1990 VN Commodore

[paulisdead]

Ok, so after running the car until it overheats I've checked relays and fuses which are ok. Next I hooked up the fan to an external power source and it works. I then checked the termo element at the rear of the engine via a multi meter and some boiling water and it gives a reading.

Is there something I'm still overlooking?

Also can I hard wire the fan in anyway (until I can $$$ for repairs)?

As said above in dact there a thread in this section regarding same sort of issue in which i posted some info.

Put the car diagnostics mode see if fans comes on it should if not then theres a wiring issue of some sort.

If you have checked all the wiring and fan doesnt come yet it works as you stated i'd be suggesting try replacing the ecu with a knnown working one and see if it works then

Hey man I think maybe change your temp sensor unsure in the vn's if there are two, one at the front of the engine and one at the back the one at the front is right behind the alternater.
