The temperature sensor may not activate the fans due to several reasons, such as a malfunction or calibration issue within the sensor itself, preventing it from accurately detecting temperature changes. Additionally, if the system's temperature threshold settings are incorrectly configured, the fans may not engage even when temperatures rise. Other potential causes could include electrical issues, such as a blown fuse or wiring problems, which can disrupt the communication between the sensor and the fan control system. Lastly, the fans themselves may be faulty or disconnected, leading to a failure in activation despite the sensor's readings.

Have a 2000 Silhouette the cooling fans wont come on unless the ac is on?
If the cooling fans in your 2000 Oldsmobile Silhouette only engage when the AC is on, it could indicate a problem with the engine's temperature sensor, the fan relay, or a wiring issue. Typically, the cooling fans should activate based on engine temperature, not solely on the AC. You may want to check the coolant temperature sensor and the fan relay for proper functionality. If you're unsure, it might be best to consult a mechanic for a thorough diagnosis.
The cooling fans on a 2001 Chrysler lhs do not turn on. Both relays work as does the cooling fans. Why then will the fans not turn on when the car gets too warm?
If the cooling fans on a 2001 Chrysler LHS do not activate despite functioning relays and fans, the issue may lie in the temperature sensor or the engine control module (ECM). The temperature sensor may not be sending the correct signal to the ECM, preventing it from triggering the fans. Additionally, wiring issues or a blown fuse in the circuit could also disrupt the power supply to the fans. It's advisable to check these components for faults to diagnose the problem accurately.

What does a Coolant Temperature Sensor do?
the coolant temp sensor( cts) reads the temp of the engine and adjust the fuel air mixture depending on the temp. if its cold out the sensor will adjust for more fuel to ease the start of the engine. ADDITIONAL: The Coolant Temperature Sensor measures the temp of the coolant, not the engine. The sensor controls the thermo fans on/off. depending upon temperature. The actual engine temperature sensor is on top of the engine and does not control the fans. If the fans do not switch on at any temperature, disconnect the 2 wire connector from the sensor (Usually at the bottom of the radiator) If fans start up with connector disconnected, replace the sensor.
