Thx for the update 89fivethreefive
I m guessing my resistor is also gone. With you would the fan only run on fast when you jumped either wire or was it like mine which is only triggered by the black/grey wire is jumped to the brown wire and nothing when I jumped the black/green wire to the brown one?
I asked the stealers to check the wiring on the fan and they said it all checked out fine but I don t really trust them.
Does any one know if the aux fan is triggered only by the radiator sensor or is it triggered by the engine heat sensor too?
