The engine computer uses the coolant temperature sensor to decide when to activate the radiator fans. That sensor is the two wire one near where the upper radiator hose attaches to the engine.The engine computer uses the coolant temperature sensor to decide when to activate the radiator fans.

On a 1996 Pontiac Grand Prix, the temperature sensor for the radiator cooling fans is typically located near the engine coolant outlet or in the engine block, often near the thermostat housing. This sensor monitors the engine temperature and signals the cooling fans to activate when the temperature reaches a certain threshold. It's important to consult the vehicle's service manual for the exact location and specifications, as there can be variations depending on the engine type.
On a 2001 Subaru Outback with a 2.5-liter engine, the temperature sensor for the cooling fans is typically located near the engine's coolant outlet, often in the cylinder head or the radiator. This sensor monitors the engine's temperature and signals the cooling fans to activate when necessary to regulate engine temperature. It's important to consult the vehicle's service manual for precise location details, as there can be variations based on specific models and configurations.
The temperature sensor activate the fan. Unless it was hot wire by a back yard mechanic.
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.
If the cooling fans on your 2004 Mitsubishi Outlander are not working when the air conditioning is switched off, it may be due to a faulty cooling fan relay, a blown fuse, or an issue with the temperature sensor. The fans typically activate based on engine temperature, so if they aren't functioning, the engine may overheat. It's advisable to check the fuses and relays first, and if those are intact, consider having the temperature sensor and wiring inspected by a professional.

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.
Check the temperature sensor
The cooling fans on a 2002 Grand Am GT might not be working because of a problem with a fuse. There is also a temperature sensor in the engine that tells the fans when to come on. This sensor may be bad.
Your temperature sensor or a fuse is bad.
No, the temperature sensor switch and the fan switch are not the same. The temperature sensor switch detects the temperature of a system (like an engine or HVAC) and sends a signal to activate or deactivate other components based on that temperature. In contrast, the fan switch specifically controls the operation of a fan, either turning it on or off in response to signals from the temperature sensor or other controls.
