Are you talking about the radiator fan? What sending unit are you talking about? There is no sender on the fan.

Which sender did you unplug? You know the fan is only supposed to come on with the ac or the cooling system temperature reaches 228. What exactly is your problem. Elaborate as much as possible. Thanks

UNFORTUNATELY YOUR AT THE POINT WHERE YOU NEED TO HOOK UP A SCAN TOOL AND LOOK AT THE VALUES AND SEE WHAT THE COMPUTER IS READING. DOES IT OVERHEAT IF YOU LEAVE THE FAN ON?

WELL IF YOUR COOLANT TEMP SENSOR IS GOOD AND IT DOESNT OVERHEAT WITH FAN ON. IF YOUR RADIATOR CAP DOES NOT HOLD PRESSURE YOUR CAR WILL OVERHEAT AT 212 DEGREES, BEFORE THE FAN IS TRIGGERED. TRY A RADIATOR CAP. THE REASON IS WHEN YOU PRESSURIZE YOUR COOLING SYSTEM IT RAISES THE BOILING POINT 3 DEGREES FOR EVERY POUND OF PRESSURE YOU PUT ON THE SYSTEM. I HOPE THIS MAKES SENSE.
