I put the car away for the night, but I did do some of this earlier. When I jump the switch the fan does not come on. I also don't remember hearing a relay click. I'll try putting 12 volts to the resistor tomorrow. I did check the resistor for continuity and it was OK. Also as I previously stated the fans do come on high if I pull the wire from the two prong sensor on the cylinder head, so I know the fans are OK
