not one single fan working

[smp009]

Hey all my good friend owns a 2006/07 VZ S pac ute, V6 model and he is having an issue with fans
the iss is simple, the fans don't work, not even the in cab fans, none nadda,zilch. no thermo fans. yet heres the snag.
if you unplug the fan plug (on the radiator) and wire it direct to the battery they work. but not when there plugged in (yes we have tested the plug),and all the relays have been replaced,along with fuses. its basically a bit of a head #### to find the issue lol

he got one of those thermo over ride switch thingys and not sure how to hook the damn thing up

basically we need help on this matter please,so if anyone has any suggestions on what the issue is that would be greatly appreciated

Sorry the only advice I can offer is plugging in a tech II and looking for trouble codes. I know, not that helpful.

fans ain`t switched on until engine temp is above 104 deg. or aircon is warm. read this post:

Temp sensor, which in theory should command them on if its not getting a signal. Which then leads back to a possible ECU fault. Given you've replaced all 3 relays with the correct type.
