There is a Cylinder Head Temperature Sensor on each head that the COMPUTER uses to determine when to cool the engine. The computer controls the fan EXCLUSIVELY! I work on a fleet of 800 Ford Crown Victoria Police Interceptors: 2002 to 2013 - same car - different decals - we have cooling fans fail regularly. THE COMPUTER CONTROLS THE FAN BASED ON CYLINDER HEAD TEMPERATURE AND AC DEMAND. NO THERMOSTATS - NO SWITCHES - JUST THE PCM. ......(Tracy Hooks)
So I wonder what the 6th one from bottom on left is? #102 says cooling fan relay
I just fixed mine by swapping the fan relay (102, thank you FordNut) with the one for the police light bar (109).
