no switch,fan control is determined by the engine control unit with input from the coolant sensor
A photocontrol uses light to activate the switch. When the sensor does not detect light the circuit is broken and the switch is deactivated.
cruise control switch
There is a Blower Motor Resistor Pack. Either the blower motor speed control switch itself is defective or the Resistor Pack is bad.
Temp sensor is next to the thermostat housing. Relay is in the fuse box. Computer is in control. There is no temp switch.
The transmission range sensor or(manual lever positioning sensor)is on your transmission where the shift cable or linkage goes into your transmission.It functions as a park and neutral safety switch (start circuit),reverse light switch,and provides information to the power train control module (what gear is selected).
I believe that used to be called the brake pressure switch and is now called the speed control deactivation switch ( even if you don't have cruise / speed control )
There is no temperature control switch for the cooling fans. The PCM Power control module receives input from the temperature sensor on the water outlet housing. The PCM turns on the fans when the temperature reaches 210 degrees through the CCRM.
That would be an O2 sensor, it monitors the oxygen level in the exhaust and sends that info to the ECM (Engine Control Module).
If a 1985 Ford F150 5.8, with a replaced speed sensor, cruise control surges and with a working pedal switch, it is due to vacuum leak. Check on the cruise box under the hood for any leaks.

The speed sensor wire is connected to the speed sensor and goes to the speed sensor relay switch. The speed sensor relay switch is connected to the computer by a separate wire.
