might sound silly mate, but are the thermos plugged in? not bein a silly bugger ay, it happened to me and somehow theyd come unplugged. if thats not it trace the wires coming out of it and see if one isnt plugged in or broken or something.
keepin' it real
hey man i have the same problem today.. got extremely hot within 20mins of driving. my fans dont turn on but will check the thermos plug tomorrow otherwise will check whole system.
cheers

we were playing hoon checkers! did you here all V8's screaming every move!
Check the ground wire from the ecu which should be BLUE & WHITE.
Im sure if you run a seperate ground wire from the blue & white at the relay, straight to the chassis, the thermos will work.
Ive have the same problem, checked all the wires but they buzzed out ok, but when I run a seperate ground straight from the relay to the chassis the fans seem to work ok, which suggests to me its a ecu ground switch problem.
Learning as I go and after installing a level 3 dash, I discovered Vns use ground switching in the ecu , which was a little bit confusing at first because to you get power where you need it but things still dont work properly.
EDIT: The ECu ground at the relay is terminal 85 I can send you a diagram just Pm me a email addy.
The above method will cause your fans to run all the time which isnt that good, as it will eventually melt either the fuse housing or the relay block.

Cruizin' in style!
Rig it up to a switch and whack it on the console somewherei have one in my VN took all of about 5 minutes to make (and 4 of that was drilling holes
)
email sent. edited 1 to show possible problem area.
yeah thanks for the email. turns out it was the thermostat. bought a new one and the car runs better than ever. engine an has started working too.
