I have a 98 Aurora, I have had recently the anti freeze starting to boil out of the overflow resivor, I finally have discoverd that the cooling fans are not coming on and never do i get any voltage to the coil side of the cooling fan relays, I have checked all fuses and they are O.K.


I replaced the engine coolant temprature switch, I am hoping one of the Olds wizards can help me through this, What controls those relays and is it possible to get a wiring schematicm that would make the whole process eaiser to troubleshoot.


I tested the relays and they are good, like I said there is no relay control power........please list any suggestion.
