VRTrickster 0 Posted May 19, 2007 Went out in the Rado today and suddenly the stage three fan came on constantly and only switchs of with the ignition! As soon as I turn the ignition on it comes back on, strange :? I unplugged the big plug on the back of the fan and it obviously stopped. Driving around with it unplugged also seemed to stop it cutting out, but Ill have to drive it a bit more to see if it has erradicated the stalling. Does anyone know what my problem is here, is the fan control unit faulty ? Quote Share this post Link to post Share on other sites

VRTrickster 0 Posted May 19, 2007 All temp sensors are new except the yellow and black one on the thermostat housing. I went for another drive and it didnt cut out, with the idle dropping as it should. Quote Share this post Link to post Share on other sites
RS VR6 0 Posted May 19, 2007 Maybe a bad fan control module. Also check the plug and see if any of the plastic is melted around the terminals. Quote Share this post Link to post Share on other sites
VRTrickster 0 Posted May 23, 2007 Well after changing the module for a second hand updated one, it was exactly the same ! After a bit of research, I found out that the black temp sensor on the thermostat housing is for the stage 3 fan. I unplugged the connector and the fan then died. I then took it for a spin and realized that that a faulty black sensor had been causing my cutting out problem the whole time ! Im now over the moon that my problem has been resolved, and Im not too bothered that I have replaced quite a lot of parts that didnt need changing ! At least they wont be going faulty in the near future, touch wood :lol: Quote Share this post Link to post Share on other sites
